One-tap target size70–80% looks the same as the original for most photos.
The tool finds the highest quality that fits. Very small targets also reduce the pixel size.
PNG is lossless, so quality and target size do not apply. Use resize, or choose WebP for a much smaller file.

Where a 50 KB limit comes up
50 KB is one of the most common upload limits on Indian application portals, because it keeps thousands of applicant photos light for the server while still showing a clear face. You will meet it most often on bank recruitment forms. The 2026 notices for IBPS PO, IBPS Clerk, SBI PO and RBI Assistant, for example, ask for a photograph of 20 to 50 KB. Some state recruitment boards use a 50 KB ceiling for signatures as well, such as the 30–50 KB signature in the UPSSSC PET 2026 notice.
Those exam forms also fix the pixel size, so for them the exam photo and signature resizer is the better tool: it crops to the exact pixels and lands inside the full KB range. This page is for every other case where the only rule is "maximum 50 KB": a profile photo on a job portal, a college admission form, a scholarship application, a society registration or an office ID card request.
How to get a photo under 50 KB
- Add the photo. The 50 KB target is already selected. You can add up to 20 images, and each one is compressed on its own.
- Check the result. Each row shows the old size, the new size and the pixel size. A green line means it is smaller than before.
- If it looks soft, reduce the pixels. Enter a maximum width of around 400 to 600 pixels. In our tests with ordinary phone portraits, a photo about 400 pixels wide fitted under 50 KB at good quality, while a full-size phone photo had to drop to very low quality to fit.
- Download the image, or all of them as a ZIP file.
Why the same 50 KB looks better on a smaller photo
A file size limit is a budget. A modern phone photo has 12 million pixels or more; a 400 × 500 pixel photo has 200,000. Spread the same 50 KB over the smaller photo and every pixel gets far more detail, so faces stay sharp and you avoid the blocky patches that appear when JPG quality is pushed too low. Online forms show your photo small anyway, so the extra pixels add nothing.
Detail also matters. A face against a plain light wall compresses easily. The same face in front of leaves, a patterned curtain or a crowded shop needs more KB for the background alone. If you are taking a fresh photo for a form, a plain background helps the file size as well as the look.
Quick checks before you upload
- Format: keep JPG unless the form says otherwise. Many portals reject WebP and PNG.
- Minimum size: if the form gives a range such as 20–50 KB, make sure the result is not below the lower number. The photo resizer can raise a small JPG to a minimum without changing the picture.
- Orientation: phone photos are turned the right way up automatically, so what you see in the preview is what gets saved.
- Documents: for a scanned page, 50 KB is tight. Try 100 KB first if the form allows it, so the text stays readable.
Everything happens in your browser. Your photos are not uploaded, there is no sign-up and no watermark, and closing the page clears them.

Frequently asked questions
How do I reduce a photo to exactly 50 KB?
Add the photo here; the target is already set to 50 KB. The tool searches for the highest JPG quality that stays at or under 50 KB, so most results land a little below it, such as 47–49 KB. Forms check a maximum, so slightly under is what you want.
My form says 20 KB to 50 KB. Will this work?
Usually yes, as long as the result is above 20 KB. If a small photo comes out under the minimum, use the photo resizer on this site with a KB range of 20 to 50; it can add harmless padding to reach the minimum. For exam forms, the exam photo resizer also sets the exact pixel size.
Why does my photo look blurry at 50 KB?
A large phone photo has millions of pixels, and squeezing all of them into 50 KB needs very low quality. Set a maximum width of about 400 to 600 pixels first. Fewer pixels at good quality look much better than many pixels at poor quality.
Can I compress a PDF to 50 KB here?
No, this page works on images only: JPG, PNG, WebP, and HEIC in Safari. For a document, save or scan each page as a JPG first, compress the images here, and then combine them into a PDF with the JPG to PDF tool on this site.
Is my photo uploaded anywhere?
No. The compression runs inside your browser on your own phone or computer, and nothing is sent to a server. The photo is gone when you close the page, so download your result first.
