Image Compressor
The Image Compressor reduces the file size of JPG and PNG images while preserving visible quality - and it works entirely in your browser, with no upload.
Smaller images, same look
Large images slow down web pages and fill up storage and inboxes. The compressor re-encodes your image at an optimised quality level, cutting the file size - often by 50% or more - with little or no visible difference. You can adjust the quality to balance size against fidelity and see the savings before you download.
Where it helps
- Speeding up websites by shrinking image weight.
- Meeting upload size limits on forms and portals.
- Emailing photos without hitting attachment caps.
Because compression happens on your device, even sensitive images stay private. To also change dimensions, use the Image Resizer.
Frequently Asked Questions
How much smaller will my image get?
It varies by image, but reductions of 50% or more are common with little visible quality loss.
Does compressing reduce image quality?
Some quality is traded for size, but at sensible settings the difference is usually imperceptible. You can adjust the balance.
Are my images uploaded to compress them?
No. Compression runs in your browser, so your images never leave your device.
What is the difference from resizing?
Compression lowers file size at the same dimensions; resizing changes the pixel dimensions. You can do both.
