Frequently Asked Questions
Is this image compressor completely free? ▾
Yes, 100% free with no hidden limits. No account required, no watermarks added, no file size restrictions. Compress unlimited images for free.
Is my image uploaded to any server? ▾
Absolutely not. All compression happens locally in your browser using JavaScript's Canvas API. Your images never leave your device. This is completely private and works offline too.
What formats can I compress? ▾
You can compress JPG, PNG, WebP, GIF, BMP, and TIFF files. You can also convert between formats – for example, convert a large PNG to WebP for maximum web performance.
How much will my image size reduce? ▾
Typically 40–90% reduction depending on the original image and quality setting. A 3MB photo can often be reduced to under 400KB while remaining visually crisp. WebP format gives the best compression ratio.

Yes! Select multiple files or drag and drop a batch of images. Use "Compress All" to process them simultaneously, then "Download All" to save as individual files.
What quality setting should I use? ▾
For web use: 70–80% is ideal. For email attachments: 60–70%. For social media: 75–85%. If you need print quality: 85–95%. The sweet spot for most uses is 75%.
