Overview
This tool reduces image file size while letting you control the result. It runs locally in your browser, so the image stays on your device while you adjust compression and inspect the output. Use it when a product photo, screenshot, banner, or graphic needs to be lighter for a website, a form, an email attachment, or a shared document. You can compare the original and compressed versions and choose the best balance between smaller size and visible detail for that file. It supports JPG, PNG, and WebP, which makes it useful for both photographs and interface graphics. If an image is already tightly optimized, the savings may be modest, but you can still fine-tune quality to avoid visible artifacts.
Use cases
- Shrink product photos for a catalogReduce large product images so listing pages load faster and media files stay lighter.
- Prepare screenshots for bug reportsCompress interface captures so support tickets and issue reports are easier to attach and review.
- Meet strict upload limitsMake document photos, ID images, or project assets small enough to pass tight file-size rules.
- Lighten newsletter graphicsCut the weight of banners and thumbnails before placing them in email campaigns.
How it works
- 1
Add a JPG, PNG, or WebP image from your device.
- 2
Adjust the quality setting until the file size and appearance look right.
- 3
Review the compressed preview and the size change.
- 4
Download the compressed image as a new file.
Examples
High-detail product photo
Input: 6.4 MB JPG, 4000 × 3000, daylight shot
Output: 1.1 MB JPG with most visible detail preserved
Useful when a catalog image is too heavy for a product page or listing.
App screenshot with flat colors
Input: 2.8 MB PNG, flat colors, transparent toolbar area
Output: 640 KB PNG with reduced file size
Best when you need to keep the layout clean while lowering weight.
Hero banner for a campaign page
Input: 1.9 MB WebP banner with soft gradients
Output: 780 KB WebP optimized for delivery
Helps reduce the size of a marketing visual without changing format.
FAQ
Does compression happen on my device?
Yes. The image is processed in your browser, so the file does not need to be uploaded to produce the compressed result.
Why can the preview look a little different from the original?
Compression can slightly alter fine texture, gradients, and sharp edges. If that happens, raise the quality until the result looks acceptable.
Which files work best here?
JPG, PNG, and WebP are the main supported formats. JPG usually shrinks well for photos, while PNG is better for flat graphics or transparency.
Will PNG transparency stay intact?
If the source image has transparency and the output format supports it, transparent areas should remain intact. Very aggressive compression can still soften edges.
Why is the file sometimes not much smaller?
Already optimized images, tiny files, or noisy photos may not shrink much. In those cases, lower quality further, but expect more visible loss.
What happens if I compress text-heavy screenshots too much?
Small UI text and thin lines can become blurry or blocky. For screens with labels, reduce in small steps and stop while the text still reads clearly.
