Compress Image to 100KB

Compress any photo to under 100KB (102,400 bytes) in your browser. Ideal for online application portals, passport uploads, and form attachments with strict 100KB limits.

• Automated binary-search quality solver targeting ≤ 100 KB (102,400 bytes)
• Optional smart dimension downscaling if quality alone cannot reach 100 KB
• Explicit verification badge showing exact final KB and byte count
• Preserves aspect ratio and lets you choose background fill for transparent inputs

Frequently Asked Questions

How does the tool guarantee the output is under 100KB?

The compressor tests multiple encoding quality levels using binary search in your browser. If even low quality exceeds 102,400 bytes on a high-resolution image, it progressively scales pixel dimensions until the blob size is strictly ≤ 100 KB.

What happens if my image is already smaller than 100KB?

The tool detects that your file already satisfies the 100 KB constraint and notifies you so unnecessary lossy re-compression is avoided.

Will compressing to 100KB make text in scanned documents blurry?

For high-resolution document scans, keep "Allow automatic dimension scaling" enabled only if required, or crop excess margins first using the Image Cropper.
