Questions

Are my images uploaded anywhere?
No. The browser decodes and re-encodes them, and the page makes no request carrying your files.
Which formats can I convert?
PNG, JPG and WebP both ways, plus any mix of them into a single PDF. GIF converts from its first frame; HEIC depends on your browser.
Is there a file size or count limit?
No server limit — the work happens on your device. The page accepts up to 20 files per run.
Does converting change the image size?
The pixel dimensions stay the same; only the file size changes. Each result shows the before and after size.
Is it really free, with no watermark?
Yes. No account, no watermark, no paid tier on this page.
Why does a JPG lose transparency?
JPG has no alpha channel, so transparent areas are flattened onto white. Choose PNG or WebP if you need transparency.
