Frequently Asked Questions

• How does the image compressor work?

  Our compressor uses the HTML5 Canvas API and browser codecs to re-encode your images at the quality level you choose. Everything happens locally in your browser — no file is ever sent to a server.

• Will my images lose quality after compression?

  With lossy compression some quality reduction is expected, but at 70–80% quality the visual difference is almost imperceptible. Lossless mode preserves exact quality while still reducing file size in many cases.

• What formats can I compress?

  You can compress JPG, PNG, and WebP images and export the result in any of those three formats.

• Is there a limit on how many images I can compress?

  No limit at all. You can drop as many files as you like in a single session. The only constraint is your device's available memory.

• Which quality setting should I use?

  For web images, 70–80% quality offers the best balance between file size and visual fidelity. Use 90%+ for print or archival purposes.

• Is WebP better than JPG for compression?

  Yes. WebP typically achieves 25–35% smaller files than JPG at equivalent visual quality, making it the recommended format for websites.
