Compress image to
50KB online.
Compress a photo to a 50KB JPG — the sweet spot for passport-style form photos: small enough for strict government and exam portals, but still clear enough to show a face. Runs privately in your browser, no signup.
Need a different limit? Try 20KB JPG, 30KB JPG, FBISE 40KB JPG, or 100KB JPG. Need iPhone HEIC photos as JPG first? Use the HEIC to JPG converter.

About this tool
Use this 50KB image compressor when a passport-size photo or scanned form must come in at 50KB or less. It is the size many Pakistani and Indian government, exam and job forms settle on — light enough to pass, but roomier than a cramped 20KB or 30KB photo, so the face stays recognisable.
Who needs this tool?
- Applicants uploading a 50KB passport-style photo to a government form
- Candidates on exam and recruitment portals that cap photos at 50KB
- Anyone needing a small JPG that still keeps the face clear
Use it safely
When should you choose 50KB?
| Situation | Best action |
|---|---|
| Passport-style form photo | Crop to head-and-shoulders first, then compress the JPG to 50KB. |
| Form asks for a JPG under 50KB | Upload the photo, hit the 50KB preset, and use the downloaded JPG. |
| Form shows exact pixels too | Resize to those pixels first, then compress the resized image to 50KB. |
| 20KB or 30KB came out blurry | Step up to 50KB where the portal allows it — the extra space keeps the face sharper. |
There is no single official 50KB rule across every website — it is just a common limit for passport-size photos on strict forms. Always follow the exact file size, format, and pixel instructions shown on your current form.
How to compress an image to 50KB in JPG
A 50KB JPG holds a clear head-and-shoulders portrait as long as you crop tight and keep the dimensions modest — roughly 600px on the long edge is plenty for a form photo. Drop your picture above, keep the 50KB preset, and the tool lands within a couple of KB of the target. If the result still looks soft, the original was probably very large; crop out background or resize first, then compress again for a cleaner 50KB JPG.

Where 50KB comes from
Forms that ask for a photo up to 50KB
Most "50KB" rules are really a 20–50KB range: the photo has to be big enough to be clear and small enough to upload. These are the usual photo specs; limits change between notifications, so always check the one you are applying to.
| Form | Photo pixels | File size | What to do |
|---|---|---|---|
| SSC (CGL, CHSL, MTS) | 200×230 px | 20–50 KB | Set 45KB |
| IBPS (PO, Clerk) | 200×230 px | 20–50 KB | Set 45KB |
| SBI (PO, Clerk) | 200×230 px | 20–50 KB | Set 45KB |
| RRB (NTPC, Group D) | 200×230 px | 15–40 KB | Use 35KB instead |
| FBISE (Pakistan) | — | Under 40 KB | FBISE page |
| PPSC (Pakistan) | — | Under 25 KB | PPSC page |
Need the photo and signature together? The photo and signature merger has SSC, IBPS and RRB presets. For the signature alone, use the SSC signature converter (140×60 px, 10–20KB).
Why aim for 45KB, not exactly 50KB
Two kinds of "KB"
Some portals count 50KB as 51,200 bytes, others as 50,000. A file of 50.5KB passes one and fails the other. Staying at 45–48KB passes both.
Windows rounds differently
File Explorer shows sizes rounded up, so a 49.2KB file can show as "50 KB". The size shown in the tool is the exact one.
Quality barely changes
The difference between a 45KB and a 50KB JPG is invisible on a form photo. Type 45 in the custom box for a safe margin.
Which pixel size fits in 50KB?
KB and pixels are different limits. The more pixels a photo has, the harder the compressor has to squeeze it to reach 50KB. Rough guide for a head-and-shoulders JPG:
| Photo size | At 50KB | Advice |
|---|---|---|
| 200×230 px | Usually lands at 15–35KB even at high quality | Fits easily. If it comes out under 20KB, see the FAQ below |
| 350×450 px | Fits at good quality | Best all-round size for a 50KB form photo |
| 600×800 px | Fits, with light compression | Fine for most portals; crop tight around the face |
| 1200×1600 px and up | Heavy compression, face looks soft | Resize down first, then compress |
Compress or resize to 50KB?
"Resize image to 50KB" usually means the same thing as compressing: getting the file under 50KB. If your form also gives exact pixels, do both: set the pixels in the image resizer first, then bring the file to 50KB here. Not sure what you have now? The image size checker shows the pixels and KB of any photo.
FAQ
Common questions
How do I compress an image to 50KB JPG?
Upload your image, keep the 50KB preset selected, click Compress, then download the JPG. If your form also gives exact dimensions, resize or crop first and then compress.
The form says 20–50KB but my photo comes out under 20KB. What now?
This tool only makes files smaller, so start from a bigger version of the photo: use the original from your phone instead of a WhatsApp copy, or a slightly larger pixel size if the form allows it. Then compress to about 45KB and it will land inside the range.
What is the difference between 50KB and 50,000 bytes?
Some portals treat 1KB as 1,024 bytes (so 50KB is 51,200 bytes) and some as 1,000 bytes (50,000 bytes). Aim for 45–48KB and your file passes on both.
Can I resize a photo to 50KB on my phone?
Yes. Open this page in Chrome or Safari, pick the photo from your gallery, keep the 50KB preset and download. It works the same on Android and iPhone, including HEIC photos.
Is my image uploaded to a server?
No. All compression happens in your browser using JavaScript. Your image never leaves your device — not even for a millisecond.
Should the 50KB output be JPG or PNG?
JPG/JPEG almost always wins at 50KB, because a passport-style portrait fits into 50KB far more cleanly as a JPG than as a PNG. If your form specifically asks for PNG, follow the form instead.
Should I resize before compressing to 50KB?
For a 50KB photo, yes. Crop to a tight head-and-shoulders portrait and bring it down to about 600px on the long edge first — that hits 50KB with a sharp face, whereas compressing a full phone photo to 50KB tends to look muddy.
Can I compress multiple images at once?
Yes. Drop or select multiple images at once and hit "Compress all". Download one image individually or use "Download all (ZIP)" to save the batch as a ZIP.
Does it work with iPhone HEIC photos?
Absolutely. HEIC files are auto-converted to JPEG before compression — no extra steps needed.
Why is my compressed image still larger than 50KB?
Some photos have too much detail or are already compressed. Crop extra background, resize smaller, then run the 50KB preset again.
Can I use this for passport, admission, or job form photos?
Yes — 50KB is a common limit for passport-size photos on exam, recruitment and government forms. Just confirm your form allows 50KB and check whether it also fixes an exact pixel size before uploading.
Is this tool really free?
Completely. No account, no watermarks, no usage caps. Files stay on your device.
