Frequently asked questions
Can I mix different input formats in one batch?
Yes — drop JPG, PNG, WebP, BMP and iPhone HEIC files together. Every file is converted to the single output format you pick, and HEIC is decoded right in your browser.
Which output format should I choose?
WebP gives the smallest files for websites and keeps transparency. JPG is the safest for forms, portals and older software. PNG is lossless and best for graphics, screenshots and logos.
Are my images uploaded to a server?
No. SqueezePix runs entirely in your browser — files are opened and processed on your own device and never transmitted anywhere. You can even load the page, go offline, and keep working.
Is there a limit?
The free plan processes up to 20 files per run (50 MB per file), with no daily cap. An unlimited batch is planned for the Pro subscription.
