Reduce JPG, PNG and WebP file size with presets, custom quality or a target size. Compare each result before downloading it.
Up to 50 files and 250 MiB in total (1 MiB = 1,048,576 bytes). The per-file limit also applies. Large dimensions or limited device memory can cause a smaller job to fail.
You can select multiple files at once.
JPG, PNG, WEBP · Up to 30 MB per fileWe made the source files, measured the exported bytes, and published the results so you can check them yourself.
Choose a simple preset or fine-tune the result.
The tool re-encodes supported images and can use repeated quality adjustments to approach a target size.
Smaller images upload faster and use less storage and bandwidth.
The best setting depends on image content and display size.
Images are compressed locally in your browser without a server upload.
No. Check the target status, exact result bytes and image quality before submitting. Targets use binary units: 500 KiB = 512,000 bytes, 1 MiB = 1,048,576 bytes and 2 MiB = 2,097,152 bytes. A destination may use decimal units; a 500,000-byte limit is smaller than our 500 KiB preset. Compare its stated byte limit with the actual result.
Quality-only presets keep dimensions. Target-size mode may downscale when quality adjustments alone cannot approach the requested size, and the result reports its actual dimensions.
The source may already be highly optimized or the selected quality may be too high to save space.
