Default settings: fit-to-image pages with lossless quality. Switch to A4 or Compact in the controls above if you need printable or smaller output.

How to convert images to PDF

Four steps, none of which involve a server. Your images stay in this tab from start to finish.

  1. Add your images

    Drag pictures onto the box above, click it to browse your device, or paste a screenshot with Ctrl+V (Cmd+V on Mac). PNG, JPG, WebP, HEIC, AVIF, GIF and BMP are all accepted — up to 50 images per PDF, 50 MB each.

  2. Arrange and rotate

    The thumbnails are the page order: image 1 becomes page 1. Use the arrows to reposition, Sort A→Z for camera filenames in human-readable order, and the rotate button to fix a sideways shot. EXIF orientation is applied automatically.

  3. Pick page size and quality

    Fit to image makes each page exactly as large as its picture — best for screenshots and graphics. Switch to A4 or US Letter for printable pages. Lossless keeps every pixel intact; Compact re-encodes as JPEG for a smaller file.

  4. Convert and download

    Press Convert to PDF. The document is assembled on your device — a progress bar shows which image is being written — and the download button appears with the finished page count and file size.

Frequently asked questions

How do I convert an image to PDF?

Drop the image onto the box at the top of this page and press Convert to PDF — the download button appears a moment later. The converter accepts PNG, JPG, WebP, HEIC, AVIF, GIF and BMP, so you do not have to check the format first. Add up to 50 images if you want them all in one document.

Which image formats are supported?

PNG, JPG/JPEG, WebP, GIF, BMP and AVIF work in every modern browser. HEIC and HEIF — the default shooting format on iPhones — work in Safari and in browsers that support the codec. If a file cannot be decoded, you see a clear message on its thumbnail rather than a silent failure.

Can I combine multiple images into one PDF?

Yes. Add every image, leave “Combine into one PDF” ticked, and press Convert — each one becomes a page, in the order the thumbnails show. Use the arrow buttons to move a page, or Sort A→Z to line up camera filenames in natural order. Untick the box and you get one PDF per image, downloadable together as a .zip.

Are my images uploaded to a server?

No. Each image is decoded by your browser, drawn to a canvas and written into the PDF locally, so no file, filename or pixel is transmitted. You can verify it: open the browser's network panel while converting, or switch off your connection after the page has loaded — the converter keeps working.

Does converting to PDF reduce image quality?

Not in Lossless mode, which is the default on this page: every pixel is embedded unchanged. In Compact mode the image is re-encoded as JPEG at quality 85, which is visually identical for photographs but drops transparency. Choose Lossless for screenshots and line art, Compact for photos and scans.

Can I convert images to PDF on my phone?

Yes — this is a web page, not a native app, so it runs in Safari on iOS 16.4+ and Chrome on Android with nothing to install. Tap the drop area to reach your camera roll or Files app. iPhones shooting in High Efficiency produce HEIC, which Safari decodes natively.

What is the difference between Lossless and Compact?

Lossless embeds the decoded RGB samples with deflate compression and preserves transparency — pixel-for-pixel identical to the original. Compact re-encodes each page as JPEG at quality 85, which is much smaller for photographs but flattens any alpha channel onto white. Screenshots and logos want Lossless; photos and scans want Compact.

Can I mix different image formats in one PDF?

Yes. Drop a PNG screenshot, a JPG photo and a WebP export into the same batch — each is decoded independently and laid out as a page. The quality setting applies the same way to every page: Lossless keeps each image's pixels unchanged, Compact re-encodes all of them as JPEG.

One converter for every image format

This page is the format-agnostic entry point to the same converter that powers the PNG to PDF and JPG to PDF pages. Those start with presets tuned for their format — lossless for PNG screenshots, compact on A4 for JPG photographs — while this page starts with the neutral defaults and lets you adjust from there.

The browser decodes any image it recognises, so the converter is as wide as the browser's own codec support: PNG, JPEG, WebP and GIF everywhere, AVIF in Chrome and Firefox, HEIC in Safari. You can mix formats freely in a single batch — a WebP export next to a JPG photo next to a PNG screenshot — and each is decoded and laid out independently.

The honest limits: 50 images and 50 MB each per run, 16 megapixels per page before the browser's canvas ceiling forces a downscale, and no OCR — the pages hold pictures, so text inside them stays unsearchable. The entire PDF, down to its cross-reference table, is assembled by JavaScript in this tab rather than by a hosted API.

Your images stay on your device

There is no upload step to opt out of. Every image is decoded by your browser, drawn to a canvas and written into the PDF locally — no file, filename or pixel is transmitted, stored or looked at by us. Close the tab and the in-memory copies are gone. The converter keeps working even with the network switched off.
