Image Resize
Resize an image by pixels or target KB
Government portals, exam forms and many job sites still ask for a photograph “not more than 50 KB” or a signature “between 10 and 20 KB”. This resize tool changes width and height in pixels or aims at a file size in KB so you can meet those limits without installing an editor.
You can also resize for WhatsApp, a website banner or an email attachment. Pick an output format, preview the result and download. The work runs in the browser, which is the right place for a personal photo that will be uploaded to a form next.
If the picture includes extra background, crop first with Image Crop or Passport Photo. Resizing a full uncropped selfie to 20 KB often destroys the face. A tight crop plus a KB target looks much better.
How to reduce photo size for forms
Upload the image. Check the original width, height and KB in the sidebar. Enter the pixel size from the form, or type the maximum KB. Generate and look at the preview. If the face is still too large on disk, lower the target KB or switch JPG quality by using the compress path in the tool.
JPG is usually best for passport-style photos. PNG is better for signatures with a white background, but PNG files can stay large; if a form insists on 20 KB for a signature, JPG or a small PNG crop is more realistic.
- Resize by exact pixels when the form lists width and height
- Resize by KB when the form only lists a maximum file size
- Preview before you upload to the portal
- Keep the original until the application is accepted
Pixels, KB and why both matter
Pixels describe the grid. KB describes the compressed file. A 200×230 photo can still be 400 KB if it is saved as uncompressed PNG, and a 20 KB file can look blocky if the pixel grid is huge. Match both rules when the form gives them. If it only gives KB, start from a sensible face crop around a few hundred pixels on the long side, then compress.
Repeated save-as-JPG on the same file adds artefacts. Always start from the original camera file, crop once, resize once, then upload.
Background and format options
Some versions of this tool also help with background and output type. Use a plain background for ID photos. Convert to JPG when the portal will not accept WEBP. Convert to PNG when you need transparency and the size limit allows it.
Common Indian form limits
Limits change, so read the form. Typical patterns are a photo under 50 KB or 100 KB and a signature under 20 KB or 50 KB. SSC, banking and state exam sites often reject WEBP and HEIC, so export JPG. If the portal still fails, try a slightly smaller KB target rather than stretching the image.
If you already know the number or the portal, open a dedicated page: 20 KB, 30 KB, 50 KB, 100 KB, 200 KB, or MPESB, MPOnline, CSC, SSC and Railway photo resize. Each one starts the same compressor at that target and explains that case. For a print passport sheet rather than a portal upload, use Passport Photo.
- 20 KB — signatures and older photo caps
- 50 KB — the usual exam photograph cap
- 100 KB and 200 KB — newer portals and document images
- MPESB, MPOnline, CSC, SSC, Railway — kiosk and board-specific notes

Frequently asked questions
How do I resize an image to 50 KB?
Upload the photo, choose a target file size of 50 KB, generate and download. Crop extra background first if the face becomes too blocky.
Can I set width and height in pixels?
Yes. Enter the width and height required by the form, then download the resized file.
Is image resize free?
Yes. No login or credits.
Does resizing happen on my device?
Yes. The resize tool runs in the browser.
Which format should I download?
JPG for photographs and most exam portals. PNG for sharp signatures and graphics. WEBP for general web use if the site accepts it.
Why does the portal still reject my photo?
Check the exact pixel size, KB range, file type and colour rules. Try JPG, a slightly smaller KB target, and a tighter crop of the face.
