What is Image Compressor?
This free image compressor helps you reduce the file size of JPG, PNG, and WebP images directly in your browser. It is useful for blog images, ecommerce product images, social media assets, portfolio screenshots, and other web graphics. Smaller files can improve page speed, reduce upload time, and save storage space. Since processing happens locally in your browser, your files are not uploaded to an external server.
When image compression helps most
Compression is especially helpful for blog images, ecommerce product photos, portfolio screenshots, slide decks, social media assets, and any upload where speed or file limits matter.
Smaller files can improve page speed, shorten upload time, reduce storage usage, and make image-heavy pages feel much faster.
How to choose the right approach
For photos, lowering quality a little often saves a lot of space with only a small visual tradeoff. For PNG graphics, size savings can be more limited depending on the image structure.
A practical starting point is quality 80, then move downward only if the result still looks good at the size people will actually view.
Tips for better results
- Do not over-compress text-heavy images, because small text and sharp edges can degrade quickly.
- Product shots and portraits often work well in the 70 to 85 quality range.
- If PNG files barely shrink, try converting to JPG or WebP instead.
- Combining resize and compression often gives a much better result than compression alone.

FAQ
Are my images uploaded to a server?
No. Everything is processed locally in your browser, so your files are not uploaded to an external server.
Can I compress PNG images too?
Yes. PNG images can also be compressed, although the size reduction may be smaller compared to JPG or WebP.
What quality setting should I use?
A range of 70 to 85 is a good starting point for most images. Around 80 often gives a good balance between quality and size.
Does it work on mobile devices?
Yes. You can use it on phones, tablets, and desktop browsers that support modern web features.
