The most capable free PNG to PDF converter
PNG on PDF turns one or many PNG, JPG, WebP, GIF or BMP images into a polished PDF in seconds — without ever uploading them to a server. Everything happens locally in your browser using modern WebAssembly, which means it’s lightning fast, completely private, and free with no daily limits, no watermarks and no account.
Features at a glance
- Multi-up grid layouts — pack 1, 2 (vertical or horizontal) or 4 images per page with a configurable gutter.
- Live first-page preview — what you see is exactly what you save. Tweak any setting and watch the page update at 60 fps.
- EXIF auto-rotate — phone photos always render upright thanks to native EXIF orientation handling.
- Per-image transforms — rotate 90°, flip horizontally or vertically, convert to grayscale, auto-enhance contrast, or auto-crop white/dark borders, all with a click.

Use cases
Receipts and expense reports — drop your phone photos, pick 4-up grid, set the auto-crop toggle, and the result is a tidy expense PDF in under five seconds. Lecture handouts — combine 80 whiteboard screenshots into a clean A4 PDF with page numbers and a custom header. Photo books — pick the Photo 5×7 page size, JPEG compression, image borders, and produce a printable mini album. Document archive — set Title, Subject and Keywords so the PDF is searchable in your file system or DMS.
Privacy by design
The converter uses pdf-lib + the Canvas API directly in your browser, so your files never reach any server. There is no upload progress bar because there is no upload. The site is also a Progressive Web App: install it once and you can convert PNGs to PDFs entirely offline.
Frequently asked questions
How is this PNG to PDF converter different from the others?+
PNG on PDF is the only major free converter that runs 100% in your browser, supports 1-up / 2-up / 4-up grid layouts, auto-rotates phone photos using their EXIF data, gives you a live preview before download, lets you set PDF metadata (title, author, subject), adds headers, footers and page numbers, and offers per-image rotation, flipping, grayscale, auto-enhance and auto-border-crop — all without a single upload, watermark or daily limit.
Will the quality of my PNG be reduced?+
Not unless you ask for it. The default “Lossless (PNG)” compression embeds your images byte-for-byte. Switch to “JPEG” compression with a quality slider when you want a much smaller PDF — typical scanned documents shrink by 80–95% with no visible loss.
Can I combine multiple PNGs onto a single page?+
Yes. Pick the 2-up vertical, 2-up horizontal, or 4-up grid layout. PNG on PDF will pack two or four images per page with a configurable gutter — ideal for photo prints, contact sheets, scanned receipts and photocopy-style documents.
Will phone photos appear right-side-up automatically?+
Yes. We read each JPEG’s EXIF orientation and apply it before embedding, so portrait shots from iPhone or Android always render the right way up. You can still tap the rotate button on any thumbnail for manual rotation.
Can I add page numbers, headers and a footer?+
Yes. Open the “Headers, footers & page numbers” section and use placeholders like {page}, {total} and {date}. The header is centred at the top, the footer sits bottom-left, and page numbers go bottom-right.
Does the PDF include searchable metadata?+
Yes. Set Title, Author, Subject and Keywords in the “PDF metadata” section. Search engines and document management systems index those fields to find your file later.
Can I produce one PDF per image instead of one combined PDF?+
Yes — choose the “One PDF per image (ZIP download)” output mode and you’ll get a single ZIP archive with one ready-to-share PDF per source image.
How do I save my favourite settings?+
Hit “Save preset”, give it a name, and the entire settings panel — including layout, page size, quality, header text and metadata — is stored locally in your browser for one-click reuse later.
Can I paste an image from the clipboard?+
Absolutely. Copy any image (Ctrl+C / Cmd+C) and press Ctrl+V / Cmd+V anywhere on the page. It will be added to the queue instantly.
What is the maximum file size?+
There is no hard limit — only your device’s memory. We have tested PDF batches with 200+ smartphone photos on mid-range Android devices.
Are my images uploaded to a server?+
No. Every conversion runs locally with WebAssembly. Your PNGs and PDFs never leave your device. You can disconnect from the internet after the page loads and the converter still works.
