How does browser-based image compression work?

FixPilot compresses images directly in your browser using the HTML5 Canvas API. When you select an image, it is read locally on your device, drawn onto a canvas element, and re-exported at your chosen quality level. Your files are never uploaded to any server — the entire process happens on your computer or phone.

PNG images are lossless and cannot be compressed with quality settings. FixPilot automatically converts PNG files to JPEG or WebP format for significant size reduction (typically 60-90% smaller). You can also set a target file size and FixPilot will automatically find the right quality level.

Can I compress PNG files?

Yes! PNG is a lossless format, so FixPilot converts it to JPEG or WebP for compression. You can typically reduce PNG files by 60-90%. If you need to keep PNG format, FixPilot will reduce dimensions while maintaining quality.

What is Target Size Mode?

Target Size Mode lets you specify the exact file size you want (e.g., 500KB). FixPilot automatically adjusts the quality to hit your target size as closely as possible. Perfect when you need files under a specific upload limit.

Is there a file size limit?

Each image can be up to 50MB. There is no limit on the number of images you can compress at once. Everything is free with no daily limits.

Are my images safe?

Completely. Your images never leave your device. There is no server upload. FixPilot processes everything using your browser's built-in Canvas API. Once you close the tab, all data is gone.
