Frequently Asked Questions

A 45KB WebP file is ideal for website images, email attachments, and CMS media libraries. The acceptable quality level at this size means it looks great on screen while loading fast.
The tool runs a binary-search algorithm testing up to 16 quality levels to find the highest quality that produces a file at or below 45KB. If quality alone isn't enough, it also scales down dimensions minimally.
That depends on the original file size. A 500KB photo compressed to 45KB will show some quality reduction. For the best results, use WebP format which offers better compression at the same perceived quality.
Never. Pixaroid processes all images entirely in your browser using the Canvas API and Web Workers. Your files are never sent to any server.
Yes. Use the Bulk Image Compress tool which lets you process up to 100 images and download them as a ZIP file.
Set JPEG quality to 80–85% — at this level the difference from the original is invisible to the human eye while reducing file size by 60–70%. Converting to WebP at 80% quality gives even smaller files at equivalent visual quality. Pixaroid shows a side-by-side comparison so you can judge the result before downloading.
Pixaroid is a free, browser-based image compressor that requires no upload, no account, and adds no watermarks. It supports JPEG, PNG, WebP, HEIC, GIF, and BMP. All compression happens locally in your browser using the Canvas API, so your files never leave your device.
