Compress image to 100 KB
Compress a JPEG to 100 KB for document uploads that need a readable page: choose 100 KB, add your images, and download copies that fit with the text still sharp.
Why 100 KB is the document size
Upload forms that ask for scanned proofs, mark sheets, certificates or receipts often allow 100 KB per file, because that is where a photographed A4 page stays readable. It is also a good size for images in an email or on a web page: they open instantly on a phone and still look crisp.
What fits in 100 KB
- A photographed A4 document at around 1,000 to 1,400 pixels tall, with readable text.
- A detailed photo at about 1,000 to 1,200 pixels on its longest side.
- A full-screen screenshot of an app or a website.
- Two-sided ID cards: compress each side separately, or combine them with JPG to PDF.
For documents and receipts
- 1Photograph the page flat, in daylight, filling the frame: a sharp, well-lit page compresses far better than a dark one.
- 2Crop out the table or the background around the page before compressing.
- 3If the form takes PDF, JPG to PDF puts several pages in one file, and Compress PDF can fit it under the same limit.
Questions about compressing an image to 100 KB
How do I compress a JPEG to 100 KB?+
Choose 100 KB, add the JPEG and click Compress to 100 KB. You get a JPEG just under 100,000 bytes with the highest resolution and quality that fit.
Will the text in my document photo stay readable?+
Usually yes at 100 KB: the page keeps around a thousand pixels or more in height, enough for normal text. Very small print may need 200 KB.
Why did my 80 KB image come out larger?+
It doesn’t: an image already under 100 KB is kept exactly as it is, unless you ask for a resize or another format.
Are my documents uploaded?+
No. Compression runs in your browser and your files never leave your device.
