Target size
Results depend on the original image dimensions, format and content complexity. Very detailed images may return the closest possible result instead of an exact byte-level match.

Platform-ready output sizes
Choose a target KB or MB size and export a compressed JPG, WebP or PNG. You can switch between 20KB, 30KB, 50KB, 100KB, 200KB, 500KB, 1MB, 2MB and custom values from one page. Results depend on the original image dimensions, image detail and format. If the target is too small, the tool explains the closest result instead of promising exact byte-level output. This page is for file-size compression, not fixed pixel dimensions.
FAQ
Can this compress image to 20KB, 30KB, 50KB, 100KB, 200KB or 500KB exactly?
The tool aims to stay at or below the selected target KB. Very detailed or very large images may not reach tiny targets without visible quality loss or smaller dimensions.
Do I need separate pages for 20KB, 30KB, 50KB, 100KB, 200KB or 500KB?
No. This main tool already lets you switch between those preset sizes after upload, so you can test different compression targets from one place.
Can I compress image to 1MB or 2MB here?
Yes. Use the custom size field and enter larger targets such as 1024KB for 1MB or 2048KB for 2MB.
Can I reduce image size to 100KB or resize JPG image to 100KB here?
Yes. The same tool supports 100KB targets and works well for JPG resize 100KB or reduce image size to 100KB use cases.
Does this support JPG resize in KB or JPEG compression?
Yes. The tool supports JPG, PNG and WebP. JPG usually creates the smallest files for photos, which makes it a strong default for 50KB or 100KB targets.
Can I reduce JPG image size to 30KB, 50KB or 100KB here?
Yes. JPG is usually the most practical format for 30KB, 50KB and 100KB compression targets, and you can switch between those presets from the same page.
Is this the same as a 512x512 resize tool?
No. This page is for file-size compression. If you need a fixed pixel canvas, use the 512x512 resize pages instead.
Does Resizer.Tools upload my image while compressing it?
No. The image is processed locally in your browser and is not uploaded or stored.
Why can compression change image dimensions?
When quality reduction alone cannot reach the target file size, the tool can reduce dimensions to get closer to the requested KB size.
