How to compress images to 100KB?
When uploading scanned university transcripts, high-definition tax certificates, or personal ID documents to job application portals, you often encounter strict file size limits of **100KB**. Our browser-local tool calculates the optimal compression ratio to fit under 100KB without blurring text.
Everything runs inside browser RAM, ensuring absolute document confidentiality.
Why Compy Image is better for portal applications:
- Complete Privacy: Official documents like signatures and identity photos should never be uploaded to third-party servers. All processing is 100% local.
- No Quality Guesswork: Use our side-by-side comparison slider to inspect text legibility (signatures) or clarity (passport photos) prior to downloading.
- Instant Downloads: Simply drop your file, click compress, and receive your 100KB file in milliseconds.
Frequently Asked Questions
Will my image lose significant quality at 100KB?
While reducing files to 100KB requires compression, Compy Image uses local Canvas algorithms to discard redundancy while preserving crucial edges. Signatures and faces remain readable and clear.
Does it support signature crop?
Yes! If your signature sheet contains excessive white spacing, you can use our Image Cropper first to crop the boundaries, then compress it here.
