JPG, PNG, WebP, HEIC — one page per image, no upload
🔒 Files never leave your device — everything runs in your browser.
HEIC is what iPhones shoot; PDF is what offices, portals, and professors want. Between the two sits everyone who photographed a signed form, a receipt, an ID, or homework with their phone and now faces an upload field that rejects the format. This tool decodes HEIC right in your browser — no conversion app, no emailing yourself, no upload — and lays each photo on its own A4 page, portrait or landscape to match.
The privacy angle is not decoration here: photos that need to become PDFs are disproportionately documents — contracts, IDs, medical papers. On this site the HEIC decoder runs on your device and the PDF is assembled there too, so the originals never leave your hands. Drop several photos together and they become one multi-page document in your chosen order.

Frequently asked questions
Why do so many sites reject HEIC uploads?
HEIC is Apple's default camera format, but much of the wider software world never adopted it — many portals and office tools only accept JPG, PNG, or PDF. Converting to PDF sidesteps the problem with a format that opens identically everywhere.
Does the photo quality survive the conversion?
Yes — the HEIC is decoded at full resolution and embedded into the PDF losslessly. What your camera captured is what the page shows, including correct orientation for photos shot sideways.
Can I combine several HEIC photos into one PDF?
Yes — drop them together and each becomes a page in one document, in your selected order; the list under the dropzone lets you reorder before creating the file. Mixing HEIC with JPG or PNG in the same batch works too.
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.
