🔒 Files never leave your device — everything runs in your browser.
PNG to PDF is the screenshot workflow: evidence for a bug report, step-by-step instructions, chat receipts, a whiteboard photo cleaned up into slides. Screenshots hold whatever was on your screen — which is reason enough to build the PDF locally instead of uploading them to be processed.
Each PNG becomes its own A4 page, portrait or landscape to match, fitted and centered. PNG is embedded losslessly — text in screenshots stays exactly as crisp as the original pixels, with transparency laid onto the white page. Multiple images arrive in the order you selected them — reorder the list with the arrows before creating — and the finished PDF downloads instantly.

Frequently asked questions
Will text in my screenshots stay sharp?
Yes — PNG data is embedded losslessly, so every pixel of the original remains. Sharpness on screen and in print depends only on the screenshot's own resolution, not on the conversion.
What happens to transparent backgrounds?
PDF pages are white, so transparent regions of a PNG rest on the white page — the usual and expected look for documents. The image data itself is unchanged.
Can I mix PNG and JPG images in one PDF?
Yes — drop them together and each becomes a page regardless of format. Other image formats like WebP and HEIC work too; they are decoded on your device first.
Is my file uploaded to a server?
No. ConvertUno runs entirely in your browser on your own device. Your file never leaves your computer or phone — there is no upload at all.
Is it really free, with no watermark?
Yes. Processing happens on your device, so serving you costs us almost nothing — no watermark, no account, no file-size limit, no daily quota.
