Why compress images?
Large images slow down page loads, bounce email inboxes over size limits, and eat mobile data. Compressing before you upload keeps quality acceptable while shrinking the bytes you send.
MyWebTools runs compression in your browser, so nothing is uploaded to our servers and nothing is stored after you close the tab.
JPG vs PNG vs WebP compression
- JPEG — best for photos and gradients. Lossy compression yields the smallest files for camera images.
- PNG — lossless-friendly for graphics, screenshots, and transparency. Files are often larger than JPEG for photos.
- WebP — modern format with strong compression; good for web delivery when browsers support it.
How to reduce image size without making it look bad
- Start with quality around 80% and compare the preview before downloading.
- This tool keeps your original width and height — only file size changes. Need to change dimensions? Use the image resizer.
- Use JPEG for photos; keep PNG when you need crisp text or transparency.
- Compress once for delivery — avoid re-saving the same JPEG many times.
