Why 50 KB is the most common limit
Many recruitment and scholarship portals cap photos at 50 KB, often with a 20 KB minimum. 50 KB is enough for a sharp face photo around 500–700 px wide. If your result must stay above 20 KB, pick the 20–50 KB preset so the file lands inside the range.
Tips for a sharper 50 KB photo
- Crop first: remove background around the face or document so the budget goes to what matters.
- Use good light. Noise from a dark photo takes many bytes and compresses badly.
- Convert screenshots to JPG: PNG screenshots are large, and the tool outputs JPG automatically.
- If the form gives a pixel size (for example 200×230 px), type it under Dimensions so the photo is not scaled twice.
20–50 KB: when the form has a minimum too
Many recruitment and scholarship forms say "photo between 20 KB and 50 KB". A file that is too small gets rejected just like one that is too big, because the portal treats a tiny file as a low-quality scan. Pick the 20–50 KB preset: the tool aims just under 50 KB, and if a very plain photo comes out smaller than 20 KB it pads the file up to the minimum without changing the picture.
A worked example: passport-size photo at 50 KB
A 3.5 × 4.5 cm passport photo printed at 300 DPI is 413 × 531 pixels. A face photo of that size usually fits under 50 KB at a JPEG quality that still looks sharp, so you rarely need to shrink it further. If your form lists exact pixels, type them under Dimensions, DPI and background; to crop the photo to passport size first, use the passport size photo maker.

Compress Image to 50KB FAQs
How can I reduce a photo to 50 KB on my phone?
Open this page in your phone browser, tap Choose images, pick the photo from your gallery and press Resize. The 50 KB file is saved to your Downloads folder.
Will the image be exactly 50 KB?
It will be just under 50 KB, usually within a few KB. Portals check that the file is not larger than the limit, so slightly under is what you want.
Can I compress a PNG?
Yes. PNG, WEBP and other formats are accepted, and the result is saved as JPG because JPG reaches small sizes far better than PNG for photos.
Is it safe for ID photos?
Yes. The photo is processed by your own browser and is never uploaded, so it is safe for Aadhaar, PAN and exam photos.
Does a 50 KB photo keep enough quality for a form?
Yes. 50 KB holds a clear face photo of about 400–700 pixels wide, which is more than online forms display or print on admit cards.
My form also needs a signature under 20 KB. Can I do both here?
Yes. Resize the photo here, then open signature resize, which keeps the whole signature on a white background at 10–20 KB.
How do I compress a photo to between 20 KB and 50 KB?
Choose the 20–50 KB preset and press Resize. The result will be just under 50 KB and never below 20 KB.
Can I compress an image to 40 KB instead?
Yes. Tap the 40 KB preset, or type any number as the maximum size.
