PNG is lossless and edit-friendly, with transparency support — ideal before retouching or design work.

Photos are processed in isolation and deleted shortly after download.

Choose PNG for editing and lossless quality; choose JPG for everyday sharing and smaller files. PNG is larger but pixel-exact.

Yes — PNG is lossless, so all the detail decoded from the HEIC is preserved.

Yes — batch uploads are supported and delivered together as a ZIP.

No. At a high quality setting the JPG looks identical to the original photo. The only real change is a slightly larger file, because JPG stores the same picture less efficiently than HEIC does.

HEIC relies on the HEVC codec, which many systems lack out of the box and many upload forms reject. JPG has near-universal support built into every device and browser, so it simply opens everywhere.

Yes. Upload a whole batch of HEIC files and each is converted to JPG, then returned together as a single ZIP download so you don't have to save them one at a time.

Yes. The converter reads the orientation metadata from each HEIC file, so portrait shots stay upright in the JPG instead of appearing rotated or sideways after conversion.

Usually, yes. At the same visual quality WebP typically produces a noticeably smaller file than JPG, thanks to more modern compression. That makes it the better choice when page-load speed is the priority.

Every current browser displays WebP natively. Only very old versions miss it, and you can serve a JPG fallback for those rare cases without affecting the modern visitors who make up the bulk of traffic.

Yes, WebP supports an alpha channel. However, if your priority is lossless editing rather than small web files, a PNG conversion is the safer working format before you flatten down to WebP for delivery.

Yes. Upload as many HEIC files as you need and each is optimised to WebP, then returned as a single ZIP, so preparing a full gallery for the web takes one upload rather than many.

Pages follow the order in which you upload the HEIC files. To control the sequence, arrange or name your files in reading order first, then add them in that order and each becomes a page accordingly.

Yes. Every HEIC photo you upload becomes a separate full page in the finished PDF, which is exactly what you want for multi-page forms, receipts, or any paperwork captured page by page.

Yes. Pages are rendered at print-friendly quality, so text stays legible on paper. For the cleanest output, photograph each page flat, square, and under soft, even lighting before converting.

Yes. The source images can come from anywhere in your library. As long as you upload them together in one go, they are merged into a single PDF regardless of when or where each was taken.
