Resize your image size to 50 kB. Supports JPG, PNG, and WebP image formats.
Your files never leave your device. All compression happens locally in your browser.
Compressing images to 50 kB with MB2kB takes just a few steps. Here is how it works.
Drag and drop your image into the upload area above, or click to browse files from your device. MB2kB supports JPG, PNG, and WebP formats.
The target size is already set to 50 kB for this page. You can adjust it if needed by entering a different number.
Click the Compress button and wait a moment. The tool processes your image right inside your browser, so nothing gets uploaded to any server. Once it is done, compare the before and after results, then click Download to save the compressed image.
50 kB is one of the most requested file size limits across Indian government portals and competitive exam websites. If you have ever filled out an online form for SSC, UPSC, or any state public service commission, you have probably seen the instruction "photo under 50 kB" right next to the upload field.
PAN card applications and income tax portal registrations also commonly fall in this range. The portals accept photos up to 50 kB for ID verification, and anything larger simply gets rejected. Same goes for digital locker services and Aadhaar-linked form submissions.
Even outside of government use, 50 kB strikes a reasonable balance. Product thumbnails, profile photos for smaller platforms, and images for classified listing sites often land in this range. The file is small enough to load fast but large enough to show a recognizable face or product.
If your requirement is even tighter, the compress image to 20 kB tool handles signature uploads and smaller size limits. For slightly larger files, the compress image to 100 kB tool gives you more flexibility with quality.
50 kB is a workable target for most common photos, but the results depend heavily on what you start with. The key is keeping the image dimensions reasonable. A passport photo at 200x250 pixels compressed to 50 kB will look clean and usable. The same 50 kB budget applied to a 2000x2500 pixel photo will look soft and blocky.
If the portal specifies dimensions alongside the file size limit, resize to those dimensions first. Most exam portals that ask for 50 kB also specify something like 3.5 x 4.5 cm at 100 dpi, which works out to roughly 138x177 pixels. At those dimensions, 50 kB gives you good quality.
JPEG is almost always the right format for passport photos and ID uploads at this size. PNG can work for graphics, but for photographs JPEG handles the compression much more gracefully.

Yes, 50 kB is generally enough for a passport photo if the dimensions are appropriate. Most government portals that ask for passport-sized photos set their limits between 20 kB and 50 kB. At 50 kB with standard passport photo dimensions (around 200x250 pixels), you can get a clear and usable image.
Many Indian government portals require images around 50 kB. SSC exam applications, IBPS banking exam forms, PAN card applications, and income tax portal uploads commonly ask for photos under 50 kB. Some portals specify a range like 20 to 50 kB for photos and 10 to 20 kB for signatures.
Start by resizing the image to smaller dimensions before compressing. A 4000x3000 pixel photo will struggle to look good at 50 kB, but if you first resize it to around 300x400 pixels, the compression will produce much better results. MB2kB handles the compression step, and you can use any basic image editor to resize beforehand.
