About The Image Compressor
Reduce the file size of JPEG, PNG, and WebP images with this free online image compressor. Everything happens locally in your browser, so your photos never get uploaded to a server. Adjust the quality slider to balance file size and clarity, then download the optimized image instantly.
Why this tool is useful
- Speed up websites, emails, and apps by shrinking image file sizes.
- Free up storage on your device without paying for a SaaS compression tool.
- Your images never leave your browser — fully private, offline compression.
How it works (client-side)
- Drop or pick an image (JPEG, PNG, or WebP).
- Adjust the quality slider to control compression strength.
- The browser re‑encodes the image using Canvas/WebCodecs, and you download the smaller file.
Is there a file size limit?
There is no strict limit. Extremely large images depend on your device’s available memory, but most everyday photos compress instantly.
Are my images uploaded anywhere?
No. Compression uses the browser’s Canvas API and WebCodecs, so your files stay fully on your device. This makes the Image Compressor a private, offline image optimization tool.
What format should I export?
Use WebP or JPEG for photos (smaller file sizes), and PNG for graphics with sharp edges or transparency. All exports happen locally in your browser.
