Image Compressor is a 100% free, browser-based utility that enables you to shrink jpg, png and webp file sizes without visible loss. Unlike traditional cloud converters, all processing executes locally on your device with zero server uploads, delivering immediate results and ironclad data privacy.
About the Image Compressor
Large images slow down websites, fill up email attachments and get rejected by upload forms. The Image Compressor re-encodes your photos with a smarter quality setting and optional downscaling, typically cutting file size by 50–90% with no difference you can see.
Drop in several files at once, choose the output format and quality, and compare the before and after size of every image. Everything is processed by your browser, so private photos never leave your device.
How to use the Image Compressor
- Drop one or more JPG, PNG or WebP images onto the upload area.
- Pick the output format and adjust the quality slider (75–85% is a good balance).
- Optionally set a maximum width to downscale very large photos.
- Download each compressed image or all of them at once.

Frequently asked questions
Which quality setting should I use to compress images?
For photos, 70–85% usually gives a much smaller file with no visible difference. Go lower for thumbnails and higher for images that will be printed or edited further.
Why did my PNG get bigger after compression?
PNG is a lossless format, so re-encoding it rarely saves space. Choose JPEG or WebP output for photos, or set a max width, to get a large reduction.
Is WebP better than JPEG for web optimization?
WebP is typically 25–35% smaller than JPEG at the same visual quality and is supported by all modern browsers, making it ideal for websites.
