Image Compressor
Image Compressor lets you shrink a JPEG's file size by dialing in a quality level and watching the estimated output size update as you go. It's built for anyone who needs smaller image files fast — bloggers trimming page weight, developers optimizing assets, or anyone attaching photos to an email with a size limit.
There's nothing to install and nothing to wait on: the compression happens right in your browser tab using the Canvas API, so your photo is never uploaded to a server or seen by anyone but you.
How to Use the Image Compressor
- Open the Image Compressor tool in your browser.
- Upload the JPEG you want to shrink.
- Drag the quality slider and watch the live size estimate update.
- Download the compressed file once you're happy with the size and quality balance.
Frequently Asked Questions
Does compressing an image reduce its pixel dimensions?
No, this tool only adjusts JPEG quality (compression level), not width or height — use the Image Cropper or a resize tool if you need smaller dimensions too.
Is my photo uploaded anywhere when I compress it?
No. The compression runs locally using your browser's Canvas API, so the image file never leaves your device.
Can I compress PNG files with this tool?
This tool is optimized for JPEG quality compression; for other formats, try the Image Format Converter first to convert to JPEG.
