Compress an image to 300KB
Many upload forms reject a photo that is even slightly over the limit. This tool compresses a JPG, JPEG or PNG image to about 300KB. It is commonly used for photo and document uploads on portals with a 300KB limit.
The compressor searches for the JPEG quality that lands closest to 300KB, so you keep as much detail as the limit allows.
How to use this tool
- Upload the photo or scanned image from your phone or computer.
- Check that the target file size is set to 300 KB. You can type another value if your form asks for a different size.
- Click Compress & Download and upload the saved file to your form.
Frequently asked questions
How do I reduce a photo to 300KB?
Upload the photo, keep the target at 300 KB and click Compress & Download. The saved file will be very close to 300KB. If your form is strict about the limit, set the target a few KB lower.
Will the photo look blurry after compressing to 300KB?
For normal photos the difference is hard to notice at 300KB. Very large images lose more detail, so resize them first if needed.
Is my photo uploaded to a server?
No. The image is compressed inside your browser and the file stays on your device.
