How to Convert PNG to PDF and Combine Multiple Images
1. Drop your PNGs
Drag one or many PNG images (also JPG, WebP, GIF, BMP, HEIC) onto the drop zone above, or click to browse. Every image loads into your browser — nothing is uploaded to a server.
2. Reorder by drag-and-drop
The queue shows a thumbnail + filename for every image. Grab any row by its drag handle and drop it somewhere else in the list — the top image becomes page 1 of the final PDF.
3. Pick the page size
Auto sizes each page to its image (pixel-perfect, transparency preserved). A4 fits every image into 210×297 mm pages with margins. US Letter fits into 8.5×11 inch pages. Separate mode skips combining and produces one PDF per image instead.
4. Convert and download
Click Convert to PDF. The file is built locally in your browser and downloads immediately. No watermark, no signup, no upload.
Why This is the Best Free PNG to PDF Converter
Transparency preserved
Every other free PNG-to-PDF converter flattens your transparent pixels onto white. We preserve the alpha channel in Auto page mode, so logos, icons, and design mockups keep their transparent backgrounds intact inside the PDF — ready for overlay, compositing, or further design work.
Lossless from input
PNGs are embedded with their original lossless data intact. No quality reduction, no re-encoding, no JPEG artifacts on your sharp edges or solid colours. What the PNG looked like is what the PDF contains.
Drag-to-reorder in the queue
Most free converters combine images in upload order with no way to rearrange. We let you drag any row up or down before saving — so you never have to re-upload in a specific sequence.
Six image formats, not just PNG
PNG, JPG, WebP, GIF, BMP, and HEIC all work. Mixed batches — some PNGs + some JPGs — combine into the same PDF. Handy when your source material is a mix of screenshots, photos, and design exports.
Three page-size options, plus Separate mode
Auto (pixel-perfect), A4 (international), US Letter (North America), or Separate (one PDF per image for batch workflows). Every real use case covered.
100% local processing
Your images don't touch our servers because we don't have any for your files. Compare: Adobe, png2pdf.com, Canva, Smallpdf, and iLovePDF all upload everything. We literally cannot see your PNGs.
No file size or count limit
Drop 5 PNGs, 50 PNGs, 500 PNGs. Only bound by your device memory — typical laptop handles several gigabytes at once. Free tiers on iLovePDF cap at 25 images; Smallpdf at 2 tasks per hour. We don't.
Truly Free, Forever
No trial, no hidden paywall, no per-file charge. Convert as many images as you want, as often as you want. Ad-supported so it stays free for everyone.
No account, no email
Start converting immediately. No signup, no email capture, no credit card. The way desktop software used to work before "free trials" became traps.
The Four Modes, Explained
Auto — pixel-perfect, transparency preserved
Each PDF page is sized exactly to its source PNG's pixel dimensions. No margins, no scaling, no borders. Transparent areas stay transparent. Use when: screenshots, logos, diagrams, UI mockups, or any PNG where you want the PDF to look identical to the original image at 100% zoom.
A4 — international standard
Every page is 210×297 mm (A4), with each image fit inside with a 0.5-inch margin on a white background. Wide images get a landscape page; tall images get a portrait page. Use when: printing outside North America or sharing professionally with European / Asian / Latin-American recipients.
US Letter — North American standard
Every page is 8.5×11 inches, otherwise identical to A4 mode. Use when: printing in the US, Canada, or Mexico, or sharing with recipients who use Letter-sized workflows.
Separate — one PDF per image
Skips the combine step. Every image becomes its own standalone PDF named after the source file. Use when: preparing documents for a system that expects one PDF per attachment (government portals, legal filings, certain upload forms).
PNG vs JPG for PDF — Which Should You Pick?
Pick PNG for PDF when…
Your source has sharp edges — text in screenshots, logos, icons, diagrams, line art, UI elements. PNG preserves those edges pixel-perfect. You need transparency preserved. The image will be re-compressed later (PNG-to-anything is clean; JPG-to-anything causes generation loss). File size doesn't matter.
Pick JPG for PDF when…
Your source is photographic — portraits, landscapes, natural images with smooth gradients. JPG is dramatically smaller (typically 5–10×) for photo content at the same visual quality. We have a sibling JPG to PDF page with identical features — same engine under the hood.

Adobe ranks #1 for this query with DR 96 and only 34K monthly traffic — weaker than Smallpdf at #9 on many pages. png2pdf.com sits at #2 with 114K traffic but DR 66 and 963 backlinks. The SERP is genuinely rank-able on content depth + privacy positioning. Content is what we brought. On-page wins or it doesn't; if it doesn't, we iterate until it does.
Who Converts PNG to PDF?
Screenshots into reports
PNG is the default format every OS uses for screenshots — Windows (Snipping Tool), macOS (Cmd+Shift+3), iOS, Android. Combining them into a PDF is the single most common PNG-to-PDF use case. Auto mode keeps each screenshot at its exact capture resolution.
Logos and design assets
Designers export logos as PNGs to preserve transparency. Combining a logo sheet or brand-asset pack into a single PDF makes it easier for clients to review — and our Auto mode preserves the alpha so the logos sit transparent inside the PDF.
Technical diagrams and charts
Mermaid, Lucidchart, Draw.io, and most chart tools export PNG. Diagrams belong in PNG (sharp lines, solid colours) — and combining a set of them into a documentation PDF is faster than wrangling each separately.
Bug reports and tutorials
10 screenshots → 1 PDF that walks through a bug repro or a product workflow. Attach one PDF to a ticket or email instead of 10 loose PNGs — recipients open it once and scroll.
Form uploads and applications
Government portals (USCIS, IRS, passport agencies), university applications, and job boards typically require PDF uploads. A scanned form PNG becomes a PDF here in one click.
Receipts and expenses
Phone scans of paper receipts often save as PNG. Drop them here, drag to chronological order, export one PDF for your expense system.
Design portfolios
Designers export work as PNG. Combining them into a single portfolio PDF is easier for recipients to open and review than a ZIP of images. Auto mode keeps each piece at its intended size.
Legal and evidence
Screenshots of chats, emails, web pages — often used in disputes or filings — combined into a timestamped PDF record. Local-only processing matters when the content is privileged.
Share as a single file
Slack, Teams, and email clients preview single-file PDFs inline but collapse multi-file attachments. Combining 8 PNGs into a PDF makes the share readable without downloads.
PNG to PDF on iPhone, Android, Mac, Windows, and Chromebook
Our PNG to PDF converter works on every device with a modern browser — Windows, Mac, Linux, Chromebook, iPad, iPhone, and Android. No app install, no plugins, no admin rights. Screenshot PNGs from iOS / macOS work natively. Android PNGs (Samsung Scout, Google Drive scans, native Screenshot) all convert cleanly. Once the page has loaded you can disconnect from the internet and keep converting — everything runs locally.
How Does Browser-Based PNG to PDF Work?
Your PNG images are read into your browser's memory and assembled into a PDF right there, without ever leaving your device. PNG is embedded directly (no conversion needed, since the PDF spec natively supports it) — preserving full lossless quality and the alpha channel. WebP and GIF pass through a quick conversion to PNG first because the PDF spec doesn't embed those formats. HEIC on Safari embeds natively; other browsers convert it automatically. Each image gets its own page sized per your preset choice (Auto / A4 / Letter). The result is a standard PDF that opens in every PDF viewer ever made. No server involved — your images stay on your device.
Frequently Asked Questions
How do I convert PNG to PDF for free?
Drop your PNGs on the page above, reorder by drag if needed, pick a page-size preset (Auto / A4 / Letter / Separate), and click Convert to PDF. The file is built locally and downloaded.
Can I combine multiple PNGs into one PDF?
Yes. That's the default — drop several images, they combine into a single multi-page PDF in the order you drop them. Drag to rearrange before saving.
Does PNG to PDF preserve transparency?
Yes, on Auto page size. The PNG's alpha channel is preserved in the output PDF. On A4 / Letter modes, transparent areas render onto the white page background.
Can I reorder images before combining?
Yes. Every row in the queue has a drag handle — grab it and move it up or down. The top image becomes page 1. Individual images can be removed with the × button.
Does it support JPG, WebP, GIF, BMP, or HEIC?
Yes, all of them — including mixed batches in the same PDF. HEIC needs Safari for native handling; Chromium browsers convert HEIC to PNG automatically.
Are my PNGs uploaded to a server?
No. Conversion runs entirely in your browser. Your images never touch our servers.
What page size should I pick?
Auto for pixel-perfect output (screenshots, logos, diagrams — transparency preserved). A4 for international printing. Letter for North-American printing. Separate for one-PDF-per-image batch workflows.
How do I convert screenshots to PDF?
Drop your screenshot PNGs and pick Auto page size. Each screenshot becomes one PDF page at exact capture resolution, no borders, no scaling — ideal for bug reports, walkthroughs, or receipt collections.
Can I convert PNGs to PDF on my phone?
Yes — open this page on your phone's browser, tap Select images, pick from your Camera Roll or Photos, convert. Works on iPhone Safari, iPad, Android Chrome, and every other modern mobile browser.
Is PNG to PDF lossless?
Yes. PNG is embedded with its original lossless data intact — no quality reduction, no re-encoding, no JPEG-style artifacts.
Does the PDF have a watermark?
No. Your PDF is exactly your PNGs assembled into pages. No watermark, no inserted logos, no trailing ad page.
Is there a limit on the number of PNGs?
No artificial limit. Desktop handles 100+ images and multi-GB batches without trouble. Mobile phones typically handle 20–50 high-resolution PNGs comfortably.
Can I also convert JPG to PDF here?
Yes — mixed batches (PNGs + JPGs) work in the same PDF. For a JPG-first flow, our sibling /jpg-to-pdf page has identical features with the same engine.
Does it work offline?
Yes, once the page has loaded. The converter runs entirely in your browser.
What's the difference between this and /merge-pdf?
/merge-pdf combines existing PDFs into one PDF. This tool converts images (PNG/JPG/…) into a new PDF. For a mix — some PDFs + some images — use this tool to convert images first, then /merge-pdf to combine with your existing PDFs.
Is this the best PNG to PDF converter?
For privacy-first workflows, batch combining with drag-to-reorder, transparency preservation, and zero signup, we think so. For cloud sync across devices, Adobe may fit better. Pick the tradeoffs that match your needs — we explicitly compare every major competitor above.
