PNG, JPG or WebP files — compress multiple images at once
Tip: a photo straight out of a phone camera is often 3000–5000px wide. For most websites, 1920px max width is more than enough and cuts the file size dramatically.

Why pixel dimensions matter more than format
Converting a file to a modern format like WebP helps, but it has limits. A 3288×4932px photo has over 16 million pixels — no compression format can make that genuinely small, because there's simply too much image data. The biggest single win is almost always resizing the photo down to the dimensions it will actually be displayed at, and only then compressing it.
- A 3288×4932px JPG straight from a phone camera can be 8–12 MB
- The same photo resized to 1920px wide is roughly 0.3–0.6 MB as WebP
- Most websites never display images wider than 1920px, even on large monitors
- Smaller files mean faster page loads, lower bandwidth costs and better SEO rankings

Frequently asked questions
Why is my image still large even after converting it to WebP?
File size depends on pixel dimensions as much as format. A 3000×4500px photo will still be several megabytes even as WebP, because it has millions of pixels. Resizing it down to e.g. 1920px wide before compressing reduces the file size dramatically — often by 80–95%.
Is this image compressor really free, with no limits?
Yes. There is no daily limit, no file-count limit, and no account required. Compress as many images as you need.
Are my images uploaded to a server?
No. Resizing and compression happen entirely inside your browser using the Canvas API. Your files never leave your device.
What's a good max width for website images?
For most websites, 1920px max width covers full-screen hero images on desktop. For blog or product photos, 1200–1600px is usually plenty, and for thumbnails, 400–800px.
Will resizing make my images blurry?
No. The tool only ever scales images down, never up, so you won't get upscaling blur. Shrinking a large photo to a smaller size keeps it sharp because there's more detail than needed at the smaller size.
Can I choose the output format?
Yes. You can keep the original format, or convert to WebP, JPEG or PNG while resizing — all in the same step.
