FAQ
What is WebP and why would I need to convert it?
WebP is a modern image format developed by Google that offers smaller file sizes than JPEG and PNG. Some older apps, email clients, and editing tools don't support WebP, so converting to PNG or JPG lets you use the image anywhere.
Is pixconv really free?
Yes. pixconv is completely free with no signup required. All conversions happen in your browser, so there are no server costs passed on to you.
Does my image get uploaded to a server?
No. All image processing happens locally in your browser using WebAssembly. Your files never leave your device.
Which image formats does pixconv support?
pixconv supports 12+ formats including WebP, HEIC/HEIF, PNG, JPG/JPEG, AVIF, GIF, BMP, TIFF, and more. You can convert between any supported formats.
Can I convert iPhone HEIC photos?
Yes. iPhones save photos as HEIC by default, which many apps and websites don't accept. pixconv converts HEIC to JPG or PNG directly in your browser — no app install needed.
Is there a file size limit?
There is no server-imposed file size limit since everything runs in your browser. Very large files may be limited only by your device's available memory.
Can I convert multiple images at once?
Yes. pixconv supports batch conversion — drop multiple files at once and download them all as a ZIP.
