Photo Size Converter in KB — For Exam & Job Form Uploads

Exam and recruitment notices rarely agree on a size: one wants the photo under 50KB, the next under 20KB, and the signature somewhere in between. This converter is built around those form sizes. Pick the KB your notice lists, add your photo or signature, and download a JPG that fits — all on your own phone or computer.

To convert a photo's size in KB, choose the limit printed in your form's notice — often 20KB to 50KB for photos and 10KB to 20KB for signatures — then upload. The photo is re-encoded as a JPG just under that size, and you can switch to another size without uploading again.

100% private — your images never leave your device. No upload, no sign-up. Check it yourself: once this page loads, it works with your internet switched off.

Required photo dimensions and file sizes differ between forms and change over time. This tool helps you hit a common target, but always verify the exact requirement on the official form or notification before you submit.

Supported formats

This tool accepts JPG, PNG, WebP, HEIC as input and gives you a form-ready JPG as output. Everything happens on your device in seconds — your file is never uploaded, so there is nothing for anyone to keep.

Before you convert: get the photo right

The KB limit is the easy part. Notices also care about a recent photo, a plain light background, the face filling most of the frame, and no cap or dark glasses. Fix those in the photo itself — retaking it costs a minute, while a rejected application can cost you the attempt.

Then convert to the size, check the preview and the exact KB on the result card, and keep the downloaded file somewhere you can find it again; you may be asked for the same photo later in the process.

FAQ

Frequently asked questions

01

Does this also set the pixel dimensions my exam needs?

No — it sets the KB only. Many notices also give pixel dimensions or a ratio. If yours does, use the exam-specific photo page for that exam, which sets the dimensions and the KB together.
02

Can I use the same photo for several forms?

Yes. Upload once and tap each size you need — 20KB for one form, 50KB for another. Each version is made from your original, so quality doesn't degrade from repeated compression.
03

What size should my signature be in KB?

Whatever your notice says, commonly between 10KB and 20KB. A signature in dark ink on white paper is easy to compress, so even 10KB looks clean when it's cropped close to the ink.
04

The notice gives a minimum as well as a maximum — will this go too small?

It can, because this page only caps the size. For a band such as 20–50KB, use the 20KB to 50KB resizer, which keeps the file above the floor as well as under the ceiling.
05

My photo was taken on an iPhone — will the form accept it?

Forms usually want a JPG, and iPhones often save photos as HEIC. Upload the HEIC here and it's converted to a JPG at the size you pick, so the portal sees a normal .jpg file.
06

Is my photo uploaded anywhere?

No. The tool runs inside your browser, so your photo is read and processed on your own phone or computer and never sent to our servers or anyone else's. We never receive it, so we can't see, keep or share it — which makes it safe for sensitive documents like Aadhaar, PAN, passports and bank statements.
07

Is this tool really free? Is there a daily limit?

Yes, it's free with no daily limit. Because the work happens on your device, an extra photo costs us nothing — so there's no cap, no watermark and no account needed. Process as many files as you like.
