Your images are processed in-browser, which keeps sensitive files off remote servers.
Private browser-based workflow
Compress Images Locally in Your Browser
Most image compressors upload your files to a remote server before compressing them. PicaPic does the opposite — everything runs inside your browser tab using WebAssembly. Your images never leave your device.

Common questions
A few quick answers for the things visitors usually want to know before they try the tool.
Does PicaPic upload my files to a server?
No. Your files stay in the browser while PicaPic compresses, converts, or resizes them. That keeps the workflow private and removes the wait time of cloud uploads.
Which image formats can I use with PicaPic?
You can upload JPG, PNG, WebP, and AVIF files, then export in the format that best matches your workflow. That makes it easy to compare quality, compatibility, and final file size before downloading.
Is there a free option?
Yes. You can start on the free plan without creating an account, which makes it easy to test the workflow before deciding whether you need higher limits or batch-heavy usage.
