Compress images online for uploads, email and website pages
Reduce oversized photos for website pages, email attachments or upload forms. JPG and WebP quality controls let you trade fine detail for smaller files. Reducing dimensions can save more space when a photo is much larger than its intended display size. PNG export is lossless and does not use a quality slider.
How to use the image compressor
Open your file
Choose the original image and review its current file size.
Choose your settings
Select JPG or WebP, lower quality, and reduce dimensions if needed.
Save your result
Download and check the reported size reduction; adjust settings again if necessary.
- Adjustable lossy quality
- Resize before export
- JPG and WebP output
- Original size comparison
- No account required
When this tool is useful
Work toward a 100 KB or 200 KB upload limit
Choose JPG or WebP, reduce quality and download to check the reported size. If the file is still too large, lower its dimensions. This is a manual workflow rather than an exact-size target.
Make photos easier to email
Large camera images often contain more pixels than a recipient needs on screen. Reduce dimensions first, then choose a quality level that keeps faces and important details clear.
Prepare lighter website images
Export at a suitable display size and compare the result with your original. A compact image is useful only if text, edges and other important details remain readable.
Choose the right settings for your file
| Option | Use it for | What to know |
|---|---|---|
| JPEG quality | Photographs without transparency | Try a moderate quality setting, then inspect edges and fine textures. |
| WebP quality | Compact images with optional transparency | Useful when the website or form supports the WebP format. |
| Image dimensions | Images much larger than their intended use | Reducing width and height can save space even when quality is already low. |
Frequently asked questions
Practical answers about files, output and what this tool can do.
Can I compress to an exact size such as 100 KB?
The tool does not target an exact byte size automatically. Lower quality or dimensions, download, and use the reported size to refine the result.
Why is the compressed image larger?
Some source images are already well optimized. Re-encoding them at a higher quality or changing formats can increase size. Try lower quality or smaller dimensions.
Can I compress a PNG without a white background?
Choose WebP to use adjustable quality while retaining transparency. PNG also retains transparency but does not have a lossy quality setting in this tool.
Does image compression change the pixel dimensions?
Only if you change the width, height or percentage controls in Resize. Adjusting quality alone keeps the current output dimensions.
