Use Image Compressor in three steps
- 1
Add one or more JPG, PNG or WebP images.
- 2
Choose a target size, output format and optional maximum width.
- 3
Run compression, compare the before-and-after sizes and download the results.
A practical compressor for strict upload limits
Many forms reject an image because its file size is too large even when the picture looks normal on screen. This compressor searches for a sensible balance between dimensions and encoding quality. It first tries quality adjustments and only reduces dimensions when necessary.
JPEG is usually a good choice for photographs, WebP often produces a smaller modern file, and PNG is best reserved for graphics that need transparency or crisp flat colors. PNG output cannot use the same lossy quality control as JPEG and WebP, so target-size results can be less predictable.
What changes when an image is compressed?
Compression can remove visual detail that is difficult to notice, reduce the number of pixels, or switch the image to a more efficient file format. The tool shows the final dimensions and savings so you can decide whether the result is acceptable before using it.
For website images, matching the exported dimensions to the real display size is often more important than pushing quality extremely low. A 3000-pixel image displayed at 600 pixels wastes bandwidth even after moderate compression.
- Use WebP for modern website images when compatibility is suitable.
- Use JPEG for photos that must open in almost any app.
- Use PNG for logos, screenshots and graphics that need transparency.
