About KBfit
KBfit is a small, free web utility built for one job: getting a photo or a signature under the file-size and pixel limits that Indian exam and ID application forms enforce. It exists because those limits are strict, inconsistently documented, and most online compressors either upload your photo to a server or ignore the pixel requirements entirely.
What it does
- Compresses JPG, PNG and WebP images to a target file size in kilobytes.
- Supports a size band (for example 20–50KB) as well as a single upper limit.
- Crops to the pixel dimensions a form expects, such as 200×230 for a photograph or 140×60 for a signature.
- Shows the verified output size and dimensions before you download.
- Batches a photo and a signature together and can download them as a ZIP.
How it works
Compression runs entirely in your browser using the HTML canvas API. The page reads the file you select, draws it to a canvas at the chosen dimensions, and re-encodes it while adjusting quality until it fits the target. No image is sent to a server, because there is no server endpoint to send it to — the site is a set of static files.
You can verify that yourself: open your browser's developer tools, watch the Network panel while compressing, or load the page once, switch to airplane mode, and compress a photo.
What KBfit does not do
- It does not submit any application form for you.
- It does not store, collect, or transmit your images.
- It does not guarantee that an exam board will accept a file. It meets the size and dimension you set; the board applies its own rules.
- It is not affiliated with SSC, IBPS, SBI, RRB, UPSC, NTA, or any government body, and it does not provide official information. Always confirm requirements in the current notification.
- It cannot promise a specific file size for every possible image. Extremely detailed scans may need a smaller pixel dimension before they fit — the tool tells you when the result is still over target.
Who it is for
Applicants filling exam and recruitment forms who need a correctly sized photo or signature quickly, on a phone or a laptop, without creating an account or handing their photograph to a third party.
