Does the compressor work on mobile?

Yes — Pixaroid works in all modern mobile browsers including Chrome for Android and Safari on iOS. No app needed.

Does compressing images reduce quality?

At 80–85% quality, compression is virtually invisible to the human eye while reducing file size by 60–75%. Below 60%, you may see JPEG artefacts around edges. Pixaroid shows a side-by-side comparison so you can judge the quality before downloading.

What image formats can be compressed?

JPEG, PNG, WebP, HEIC/HEIF, GIF, BMP, and TIFF are all supported. The output format can be kept as the original or changed to JPEG or WebP for maximum compression.
