Free, browser-only, no upload needed
10KB is one of the strictest image size limits you will encounter on a portal or form. This tool reaches that target using a binary search over encoder quality combined with proportional dimension scaling for very large source files.
On-device only
No data leaves your browser
All formats
JPEG, PNG, WebP, HEIC, AVIF
Two-stage algo
Quality then dimension scaling
Drop image here to compress to 10KB
JPEG, PNG, WebP, AVIF, HEIC. All processing stays in your browser.
Three steps is all it takes. Everything runs in your browser so there is no waiting for an upload or server processing.
Set your target
The target is pre-set to 10KB. You can adjust it to any value if your portal has a different limit.
Drop your image
Drag and drop a JPEG, PNG, WebP, AVIF or HEIC file onto the tool. No upload happens. The file stays on your device.
Download the result
The tool runs a binary search over the encoder quality setting, then scales dimensions if needed. Download the compressed file immediately.
A 10KB ceiling is rare but not unusual on legacy government systems, older scholarship portals and forms that were built to serve users on very slow connections. It often appears on signature upload fields rather than photograph fields, because a scanned signature is a simpler image that compresses more aggressively.
What to expect at 10KB
At this size, a colour photograph will have visible compression and reduced dimensions. The image will still be clear enough for document submission. If quality is critical and the portal accepts 20KB or 50KB, use the higher target for better results.
A 10KB image limit is typically found on forms that collect a digital signature scan, a small avatar or thumbnail, or a supporting document where the portal was designed around very low bandwidth. Some older government portals in South Asia and Southeast Asia also impose this limit on applicant photos. It is an extremely tight target and usually results in a small-resolution output.
At 10KB, image quality is noticeably reduced compared to the original, but the image remains clear enough for identity verification and form submission purposes. A signature scan or small avatar typically survives compression to 10KB with acceptable clarity. For facial photographs, the tool will also reduce the image dimensions to meet the target.
You can upload JPEG, PNG, WebP, AVIF and HEIC files. The output is either JPEG or WebP. JPEG is recommended for submission portals because it has universal support across all systems and browsers.
No. The entire compression process runs inside your web browser using JavaScript and the Canvas API. Your image never leaves your device. You can turn off your internet connection after the page has loaded and the tool will still work.
At targets as small as 10KB, reducing encoder quality alone is often insufficient for large source images. The tool first searches for the highest quality setting that fits within 10KB. If even the lowest quality produces a file that is too large, it progressively scales down the image dimensions until the target is met. This two-stage approach gives the best possible visual output within the constraint.
