Features
What this 10KB page does that the homepage does not
Same MozJPEG Worker as compress image to 100KB. Different default, different job: exam signatures and 10KB caps, not blog images. Face photos that print 20KB belong on the 20KB exam page.
Crop the strokes, then the bytes
MozJPEG searches quality first. It scales the longest edge only if 10KB is still too small. Crop the signature or thumb yourself before that happens, or the budget is spent on white paper.
No upload of a signature scan
Encoding stays in this tab. Exam signatures and thumb impressions never go to ImageTo100.com servers. Close the tab and the pixels are gone from memory.
JPG out for old portals
PNG or HEIC can go in. The file you save is JPG, because many recruitment boards still reject WebP and PNG. This page does not write a PDF. compress image to 10kb is still a picture.
What it is
What is Compress image to 10KB?
Compress image to 10kb means shrinking a file to 10,240 bytes or less so a form that says maximum 10KB accepts it. Exam boards, scholarship portals, and old recruitment sites still print that ceiling next to a signature, a thumb impression, or a tiny avatar. One kilobyte over and the box rejects the file.
10KB is a much harder cap than 20KB or 100KB. A typical phone photo is 2–8 MB. At 10KB you only have room for a cropped signature, a thumb scan, or a tiny square face. That is why those boards use it: the file is displayed as a stamp on a form, not as a portrait.
This address uses the homepage MozJPEG Worker. The homepage H1 stays Compress image to 100KB. The 20KB exam page exists for admit-card photos. This path exists because the search said 10KB. PNG or WebP can go in. The download is JPG on purpose. Nothing is uploaded.
If the notice only says 20KB, usethe 20KB exam page. If it says 50KB, usethe 50KB page. If it says 100KB, use the homepage. Stay here when 10KB is the printed maximum.

How to
How to compress image to 10KB online
If the prospectus lists pixels, open Width × height, drop the file, leave 10KB, click Compress now. Check the size on your device before you open the exam portal.
Step 1
Crop the signature or read the 10KB line
If the portal also lists pixels (for example 140 × 60), open Width × height and type that box. Leave 10KB. A full A4 scan at 10KB will smear the ink — crop to the strokes first.
Step 2
Drop the cropped scan and leave 10
Add a JPG, PNG, WebP, or iPhone HEIC. Leave the target at 10KB. Open Width × height only if the form lists pixels. Batch up to 20 files — photo, signature, and thumb together if the packet asks for all three.
Step 3
Download and check 10KB on the device
Click Compress now. Confirm the JPG is at or under 10KB in Files or Finder before you open the exam site. Use Download all for a batch. A 9KB JPG is a pass. An 11KB file is a reject.
Why this page
Why use a 10KB-first page
Fewer “file too large” loops on a 10KB box
Old recruitment boards reject 11KB the same way they reject 2MB. A 10KB-first page removes the guess. compress image to 10kb here so you do not type 10 on a generic compressor after the portal already bounced the file.
Safer on a shared computer
Signature crops stay in page memory. Close the tab and they are gone. Do not email the original scan to a random host just to hit 10KB for an exam form.
Works after the page has loaded
A hostel or exam-center Wi-Fi can be weak. After this page loads, the MozJPEG Worker does not need to upload the scan. That matters when the library terminal is slow.
Honest when 10KB is too tight
If a 12-megapixel landscape cannot hit 10KB, you see a best-effort note. Crop tighter or raise the cap if the form allows 12KB, 15KB, or 20KB. This page does not pretend 10KB is lossless.
Limits and tips
Pro tips before you compress image to 10KB
- Crop to the ink on a plain background before you compress image to 10kb. Quality goes where the pixels are. Extra white paper spends the 10KB budget on nothing.
- Signatures are mostly white. They often sit under 10KB with little damage. Face photos do not. Use the 20KB exam page if the form allows 20KB for a portrait.
- If the form lists both pixels and 10KB, open Width × height, type 140 and 60, and leave 10KB. Closed, the tool just hits the byte cap.
- Start from the camera original or the scanner file, not a screenshot of a screenshot. Each extra JPEG pass makes 10KB look worse.
- Check the downloaded bytes on the phone. Some galleries show “KB” rounded; the portal reads the real file size. Type 8 if 10,240 bytes still fails a decimal 10,000 cap.
If the file is still above 10KB, the tool stopped before the ink turned into a smear. Crop to the strokes, then compress again. “Shrink further” will hit a tighter cap, but a face will look blurry. Raising the target only helps if the portal allows more than 10KB.
Use cases
When to compress image to 10KB — and when not to
Exam and recruitment signatures
Input: Phone photo or scan of black ink on white paper, often 1–4 MB
Setting: 10KB default on this page, plus Width × height if the form lists 140 × 60
Output: JPG at or under 10KB, strokes still readable
Caveat: Crop to the signature. A full A4 page at 10KB will smear. Check the prospectus for a minimum size too.
Thumb impression and ID scans
Input: Ink thumb on paper, or a cropped ID strip
Setting: 10KB, batch up to 20 files, then Download all
Output: Three small JPGs the packet will take
Caveat: The face photo may belong on the 20KB exam page if that line prints 20KB. Read each line.
Avatar and tight profile caps
Input: Square headshot, already cropped
Setting: 10KB if the app still asks for it
Output: Tiny JPG that loads on a weak signal
Caveat: A landscape holiday photo will look soft at 10KB. Crop to the face. Prefer 20KB or 50KB if the form allows it.
Old scholarship and government boxes
Input: Document crop or passport-style stamp
Setting: 10KB, plus pixels if printed
Output: File the upload validator will take
Caveat: Job portals that print 200KB belong on the 200KB page. Do not force 10KB when the notice allows more.

No compressor keeps a 4MB phone photo lossless at 10KB. A cropped signature or thumb scan stays readable. A full-scene portrait will look soft. compress image to 10kb without losing quality is not a lossless promise — it is the highest JPEG quality that still fits 10,240 bytes.
Can I compress image to 10kb to 20kb?
If the form says 10KB to 20KB, read the ceiling. When 10KB is the maximum, stay here and leave 10. When 20KB is the maximum, open the 20KB exam page instead of crushing a legal 20KB photo on this URL. The tool hits one number, not a sliding band.

Yes. Open Width × height, type the printed box such as 140 and 60, and leave 10KB. compress image to 10kb width and height is one download: a JPG at those pixels and at or under 10KB. Leave Width × height closed if the form only names 10KB.
Can I compress photo to 10kb, or only a signature?
Yes. A tiny avatar or a tightly cropped ID face can sit under 10KB. A full-scene holiday photo will smear. compress image to 10kb and compress photo to 10kb use the same MozJPEG Worker. Crop first. Face photos usually belong on the 20KB exam page if the form allows 20KB.
Can I compress image to 10kb pdf, or use iLovePDF?
No. This tool does not open a PDF and does not write a PDF. It is not iLovePDF. Searches like compress image to 10kb i love pdf usually want a 10KB JPG to drop into a form. Compress the picture here, then attach that JPG in the PDF tool you already use.

Can I compress image to 12kb or 15kb here?
Yes. Type 12 or 15. This page is for the 10KB job; nearby caps use the same MozJPEG Worker. We do not open a 12KB URL or a 15KB URL. Stay here, type the number, and download. Do not use this URL if you meant 100KB or 2MB.
Can I compress png image to 10kb online?
Yes. Drop the PNG. The download is still JPG so exam portals that reject PNG accept the file. A PNG logo with transparency becomes a white or flattened JPG. compress png image to 10kb online on this URL is a byte cap, not a PNG-out tool.
How do I compress image 5kb to 10kb?
If the form says 5KB to 10KB, leave 10 unless it also prints a minimum. A file under 5KB can fail some old boxes. Type 8 if you need to sit in the middle of that range. This page still hits one number at a time.
Is this 11zon or SmallJPG for compress image to 10kb?
No. ImageTo100.com is not 11zon and not SmallJPG. Those are different sites. This URL still does the 10KB job in your browser: drop the file, leave 10, download a JPG. Nothing is uploaded to ImageTo100.com servers.
What if the file is already under 10KB?
A JPG already under 10KB is kept. Do not crush it again unless the form is stricter — a second JPEG save only adds artifacts. A PNG or HEIC under 10KB is still saved as JPG so exam portals that reject PNG accept the file.
Why do exam boards still ask for 10KB?
Legacy recruitment and scholarship systems capped storage before phone cameras shot several megabytes. A 10KB signature or thumb scan is enough for a small on-screen stamp. The form never raised the ceiling. That is why compress image to 10kb is still a real search.
