Compress images and aim for 20KB, 50KB, 100KB, 200KB or any custom size.
Reduce file size in batches
Start with WebP or JPG at 70–80% quality. Limiting the maximum width often saves more space than lowering quality alone, especially for camera photos.
Settings, real-world decisions, release checks and limitations.
Reduce image size in KB for application forms, email attachments and websites. The tool can adjust encoding quality and, when necessary, pixel dimensions to approach a target such as 20KB, 50KB, 100KB or 200KB.
File size is affected by image dimensions, visual complexity, format and quality. A detailed photo needs more data than a simple logo at the same dimensions, so an exact KB target may require several controlled adjustments.
| Setting or choice | Choose it when | Trade-off |
|---|---|---|
| Target KB | Use when a form has a strict maximum | The target is approximate because images compress differently |
| Maximum width | Use for oversized phone photos | Reducing dimensions removes pixels permanently |
| JPG/WebP | Best for most photographic compression | Transparency may be lost in JPG |
| PNG | Use for line art or required transparency | Photographic PNGs may remain large |
Inspect the current dimensions and file size first.
Set the required KB target and a sensible maximum width.
Process one image and inspect faces, text and fine edges at 100% zoom.
Use the smallest acceptable result, not the smallest possible result.
Lower maximum width before using extremely low quality.
Increase width or quality, then test again.
Try WebP or JPG if transparency is not required.
No. The tool can approach a target, but content complexity and minimum usable dimensions limit the result.
For very large photos, reducing dimensions usually gives a better balance than severe quality loss.
No. Resizing is designed to preserve the source aspect ratio.
Flat colors and repeated patterns compress more efficiently than detailed textures and noise.
Confirm file type, exact byte limit, pixel requirements and readability.
