Compress image to 300KB
Use a target size and export WebP/JPG without uploading files.
TL;DR
- Size: 300KB target (best-effort).
- Format: WebP for smaller photos, JPG for compatibility.
- If still too big: downscale (max width/height).
3 steps (using this tool)
- Upload your image(s) and set Target size (KB) to 300.
- Pick WebP or JPG and adjust max width/height if needed.
- Compress and download, then verify file size.
Recommended defaults
- Format: WebP for photos, JPG for compatibility.
- Target size: 300KB
- Max quality: 90%
- Downscale only if required
Troubleshooting
- If still too big: set max width/height (e.g. 1600px).
- If artifacts: increase max quality to 95% (size may exceed target).
- If a platform doesn't accept WebP: switch to JPG.
FAQ
Do you upload my images?
No. Processing happens locally in your browser. Your files are not uploaded.
What size should I use?
Use the recommended size.
Which export format should I use?
JPG for photos, PNG for text/logos or transparency, WebP for smaller files (if supported).
Crop vs Pad — what is the difference?
Crop fills the target size (may cut edges). Pad fits the whole image and adds background/space.
How do I protect text and logos?
Keep important content centered and avoid placing critical text at the edges.
Can I batch resize?
Yes. Use the Batch Resizer to apply the same size to many images.
