FAQ

Piclizer redraws your image using your browser's built-in encoder with a quality setting you control. Lower quality means a smaller file. Processing happens entirely on your device.

At 70–90% quality, most photos look nearly identical to the original while being significantly smaller. You can preview the result before downloading.

JPG, PNG and WebP. You can keep the original format or export to a different one.

Yes — add as many files as you like and they will be processed in a batch, one after another.

No. Compression uses your browser's Canvas API. Your images never leave your device.

About this tool: Image Compressor

Smaller images without the visible cost

The Image Compressor squeezes JPG, PNG and WebP files down to a fraction of their original size while keeping them visually indistinguishable from the source. It re-encodes your pictures with an optimised quality setting, strips invisible metadata such as camera EXIF records, and only writes pixels that actually change the picture. The result is a file that loads faster, uploads on the first try, and still looks sharp at 100% zoom.

Compression quality is a sliding scale, and this tool treats it that way: dial it down aggressively for thumbnails and chat attachments, or keep it high for portfolio shots where every detail matters. Because everything runs locally in your browser, a batch of twenty photos compresses as fast as your device can process it — no upload queue, no waiting for a server, no file-size ceiling beyond what your browser can hold in memory.

If you work with images regularly, this single tool pays for itself immediately: faster websites, emails that clear attachment limits, and storage that stops filling up. Pair it with the Image Resizer to shrink dimensions first — fewer pixels means even smaller files — or convert to WebP for an extra 25–35% saving at the same visual quality.

Like every Piclizer tool, this one runs entirely in your browser — your files stay on your device.
