Resize Image to 50KB
This compressor opens with 50KB typed into its target box and JPG chosen as the output. Drop in a passport-style photo, press Compress, and the file it hands back is 50KB or smaller. The image is processed on your device, not on a server.

- RPSC RASphoto 20–50KB (50KB is the maximum)
- RRB Group Dphoto 30–70KB (inside the range); signature 30–70KB (inside the range)
Where 50KB is an exam's minimum, don't target exactly 50KB: the result is always at or below its target, so it can fail that minimum. Target a few KB above the minimum instead, for example with the 100KB page, and if a small photo still comes out under it, raise it with Increase Image Size in KB.
Limits change between recruitment cycles, so confirm them in the current official notification before you submit.
Last updated
Fifty kilobytes is the most common upper limit for an exam photograph. SSC CGL, IBPS PO and SBI PO all ask for a 20–50KB photo, and railway forms such as RRB NTPC accept 30–70KB. This page loads the image compressor with 50KB already entered, so a phone picture can be brought down to that ceiling without any settings to hunt for.
The work happens inside your browser: the photo is decoded, redrawn on a canvas and re-encoded as JPG on your own device. A 50KB budget is comfortable for a properly sized passport photo, but it is still far too small for a full-resolution camera image, which is why the guidance below starts with pixel dimensions rather than compression settings.
How it works
1. Choose your photo
Drag the picture onto the dashed upload box, or click it to open your files. Phone JPGs, screenshots in PNG, WebP and GIF are all accepted, up to 50MB per file.
2. Confirm the target reads 50 KB
Target Size is the active Compression Mode and the Enter Target Size field shows 50 with the KB button selected. Output Format stays on JPG. Typing a different number replaces the preset if your form uses another ceiling.
3. Compress and compare sizes
Press the Compress button, labelled with the number of images waiting. When it finishes, the row lists the old size next to the new one and the percentage removed, so you can see the photo now sits at or below 50KB.
4. Save the result
Download Image saves a single file and Download All saves every finished one. Each copy is named after the original with “-compressed” before the .jpg extension.
When you'd use it
SSC and banking photographs
The 20–50KB window used by SSC CGL, IBPS PO and SBI PO puts 50KB at its top edge. A 50KB target keeps the most detail the form allows while staying under the cap.
Railway forms with a 30KB floor
RRB NTPC and RRB Group D want both the photo and the signature between 30KB and 70KB. A 50KB photo lands near the middle of that window, clear of both the lower and upper limits.
Teaching and entrance applications
CTET, CUET, NEET and JEE Main accept photographs well above 50KB, yet a 50KB file still falls inside their ranges. One 50KB copy can therefore serve several applications in the same season.
Profile pictures on job portals
Recruitment and government job portals often limit profile photos to a few dozen kilobytes. A 50KB JPG keeps a face sharp at the small size those portals display it.
Re-sending an old scan
A photo scanned for an earlier application is often a flatbed scan several megabytes in size. Turning that archived scan into a 50KB copy lets you reuse it quickly, provided the notification's recency rule still allows an older picture.
What 50KB holds at exam photo sizes
A 50KB target allows 51,200 bytes, or 409,600 bits. Spread over a 413×531 photo, the 3.5×4.5 cm size many exams use, that is almost 1.9 bits per pixel, enough for a clean JPEG of a face. Over a 200×230 photo it is nearly 9 bits per pixel, so a small photo often fits at the compressor's top quality and comes out well under 50KB.
Over a 12-megapixel phone photo the same 409,600 bits work out to about 0.03 bits per pixel. The compressor keeps full resolution while it searches for a JPEG quality that fits, and only shrinks the image when even its lowest quality overshoots. A large original therefore either loses a lot of quality or gets scaled to arbitrary dimensions that may not match what the form checks.
Resize first for a predictable result. Set the exact pixel size with the Resize Image tool or the exam photo resizer, then compress to 50KB here. The photo then passes both the dimension check and the size check.
Staying inside a 20–50KB or 30–70KB window
Most exam ranges have a floor as well as a ceiling. For a 20–50KB form, a 50KB target is right: the compressor aims for between 95 and 100 percent of the target, so a full-resolution photo typically lands between about 47.5KB and 50KB, well above the floor.
For the 30–70KB railway window, 50KB gives a margin on both sides. DSSSB is the exception in the presets: its photo range is 50–300KB, so 50KB is its minimum, and a target of 100KB or more is the safer choice there.
This tool counts 1KB as 1,024 bytes. If a portal measures in thousands of bytes, a file at the very top of the 50KB target reads as 51.2KB there. Entering 48 instead of 50 keeps a strict 50KB ceiling safe under either reading.
When a signature should not be 50KB
Most signature fields are much tighter than photo fields. SSC and banking forms cap the signature at 20KB, so a 50KB signature would be rejected; use the 20KB page for those.
Railway forms are the opposite case. RRB NTPC asks for a 140×60 pixel signature of at least 30KB. At that size the raw, uncompressed colour data is only 25,200 bytes, so a JPEG normally comes out below the minimum however high the quality. Raise it with the Increase Image Size in KB tool, which pads the JPG up to a chosen size while keeping its pixel dimensions.
Frequently asked questions
Is 50KB the maximum or the minimum for my exam photo?
It depends on the exam. For the photograph it is the maximum for SSC CGL, IBPS PO, SBI PO, BPSC and RPSC RAS, sits inside the range for UPSC, RRB NTPC, NEET, JEE Main, GATE, NDA, CTET, CUET and RRB Group D, and is the minimum for DSSSB. The list on this page shows the range for each.
Why did my photo come out at 30KB instead of 50KB?
Small photos, such as 200×230 pixels, can fit under 50KB even at the compressor's highest quality, so there is nothing to gain by making them bigger. A result under the target is still accepted wherever 50KB is the ceiling.
Can I get a 50KB photo without it looking compressed?
Yes, if the photo is sized for the form first. At 413×531 pixels a 50KB budget allows a high JPEG quality. Visible blocks usually mean the image still had thousands of pixels on each side.
Will the compressed photo keep its camera details and location?
No. Re-encoding through the canvas writes a new JPG that contains only the image, without EXIF fields such as the camera model, capture date or GPS position.
Does the 50KB target work for PNG and WebP photos?
Yes. Any of those formats can be added, and with Output Format on JPG they are all saved as JPG files under 50KB. Transparent areas become white.
What should I do if the portal still says the photo is too large?
First check the file the portal received really is the downloaded “-compressed” copy, not the original. If it is, the portal probably counts kilobytes as thousands of bytes; compress again with 48 in the target box, which clears that stricter reading.
