How to Batch Compress Multiple Images in Seconds
Compressing images one at a time is fine for a single photo — but when you've got a folder of 30 to shrink for a gallery, a listing or an email, you need to do them all at once. Here's how to batch-compress in seconds, with no uploads and no per-file limits.
Batch compress in three steps
- Open the FreeCompressor image tool.
- Drag in the whole set of images at once (or select them all in the file picker).
- Set your format, quality or target size once, then click Download All. Every image is compressed with the same settings and saved.
Because it runs in your browser, there's no upload queue and no cap on how many you process — the only limit is your device's memory.
Why browser batch beats upload-based tools
- No batch limits. Upload-based tools often cap you at ~20 images per go; local processing has no such restriction.
- Faster. Nothing uploads or downloads from a server — compression starts immediately.
- Private. A folder of personal photos never leaves your device.
Tips for a clean batch
- Group similar images. Photos and graphics compress best with different settings — batch photos together (JPG/WebP) and graphics together (PNG).
- Use a target size when every image needs to meet the same limit (e.g. all under 200 KB for a marketplace).
- Spot-check the preview on one representative image before downloading the whole set.
