What this page does
This page helps meet a 100 KB file-size ceiling through visible, manual quality control. The exact output depends on image dimensions, detail and noise, so no single quality percentage guarantees 100 KB for every file.
How to use Compress Image Under 100 KB
- Upload the image and note its original size.
- Lower the JPEG quality slider gradually.
- Stop when the displayed output is below 100 KB and still looks acceptable.
- If it remains too large, resize the image dimensions and compress again.
Good uses
- Application forms with a 100 KB photo limit
- Small email or portal attachments
- Reducing photographs before upload
How to verify the result
- Confirm the displayed result is below 100 KB.
- Inspect faces, text and signatures at full size.
- Check the downloaded file size in your device file manager.
Known limitations
- Output is JPEG and transparency is not retained.
- Large dimensions may require resizing as well as compression.
- Very low quality can make text, faces and gradients visibly damaged.
Examples
- Prepare a passport-style photo for an online form.
- Reduce a scanned signature while keeping it readable.
- Compress a phone photograph before submitting it to a portal.
