About Image Compressor
Reduce image file sizes using our free online image compressor. Upload your JPG, WebP, or other images, set the quality level (1–100), and the tool recompresses each image at the target quality. Lower quality values produce smaller files suitable for web use; higher values preserve more detail for print. The compressor keeps the output in the same format as the input — if you upload a JPG you get a JPG back, preserving format compatibility. For lossless formats like PNG and GIF, a quality setting of 85 is used internally for any format conversion, but these formats are reencoded at default settings since they do not have a continuous quality parameter. All processing runs locally in your browser — no uploads, no privacy concerns, completely offline-capable once the page loads. Batch compress up to 20 files and download as a ZIP. Use the quality slider to preview the output before downloading to ensure the result meets your needs.
Frequently Asked Questions
- What quality setting should I use?
- For web images: 75–85. For email attachments: 60–75. For print: 90–100. Preview the result and adjust until the quality looks acceptable.
- Does this work on PNG files?
- Yes, but PNG is lossless — quality changes have limited effect. For significant PNG size reduction, consider converting to WebP instead.
- What is the maximum file size?
- 10 MB per file, up to 20 files at once.
