How to resize a photo in KB
- Choose the photo. Tap the box above, or drag and drop. JPG, PNG, WebP and iPhone HEIC all work.
- Set the KB limit. Type the maximum from your form, or tap a common size such as 20 KB or 50 KB. Add a minimum if the form gives a range.
- Crop if needed. Tap Crop & rotate to centre your face or straighten a sideways photo.
- Add dimensions if required. Open Dimensions & DPI and enter the size in pixels, centimetres or inches, or tap a preset.
- Download. Check the preview and the exact size in bytes, then save the JPG and upload it to your form.
Why do forms ask for an exact KB size?
Recruitment, admission and government portals receive lakhs of uploads during each application window. Fixed limits keep their storage and page loads under control, so the upload box rejects any file even 1 KB over the limit. Many portals also set a minimum so that a tiny, unreadable photo cannot be submitted.
Phone cameras save photos of 2 MB to 6 MB, which is 40 to 120 times larger than a typical 50 KB limit. Simply lowering JPEG quality is rarely enough, and lowering it too far makes faces blotchy. A good resize reduces the pixel size and the quality together, which is what this tool does automatically.
Photo resize in KB for 2026 exam forms
These limits are taken from the official 2026 notifications and information bulletins of each exam body. They change from cycle to cycle, so check the notice for the exact post you are applying for.
| Exam | Photo | Signature |
|---|---|---|
| IBPS PO, Clerk, RRB; SBI PO, Clerk | 20–50 KB, 200×230 px | 10–20 KB, 140×60 px |
| UPSC Civil Services | 20–200 KB, face at least 75%, white background | 20–100 KB, 350–500 px, three signatures |
| NEET UG, JEE Main | 10–200 KB, face 80%, white background | 10–100 KB |
| CUET UG, UGC NET | 10–200 KB, face 80%, white background | 10–50 KB |
| CTET | 10–100 KB, 3.5×4.5 cm | 3–30 KB, 3.5×1.5 cm |
| India Post GDS | 30–100 KB, 320×400 px | 20–100 KB, 300×120 px |
| SSC (CGL, CHSL, GD, MTS) | No upload: the photo is taken live in the form | 10–20 KB, about 6×2 cm |
| RRB (NTPC, Group D, ALP) | No upload: live photo | 30–49 KB, at least 140×60 px |

Many exams now also take a live photo through your webcam or phone during the form. That photo is captured by the portal itself and does not need resizing. You still need the uploaded photo where the table lists one.
Why was my photo rejected?
- The file is a few bytes over. Some portals count 1 KB as 1000 bytes, others as 1024. A file your phone shows as 49.5 KB can be 50,688 bytes, which fails a 50,000-byte check. This tool stays inside both definitions and shows the exact byte count.
- Wrong dimensions. If the form gives pixels, such as 200×230, use exactly that size. Enter it under Dimensions & DPI.
- Face too small. UPSC wants the face to cover at least 75% of the photo, and NTA exams ask for 80% with ears visible. Use Crop & rotate to crop close to the face.
- Background not plain. Most notices ask for a white or light background. A cluttered room also wastes KB that should go to your face.
- Wrong format. Portals accept JPG/JPEG. PNG, HEIC and WebP are converted to JPG here.
- Old or edited photo. NEET UG 2026 asked for a photo taken after 1 January 2026, and several exams match your photo against your face at the centre.
How this photo resizer in KB works
When you choose a photo, the tool first estimates how many bytes each pixel of your picture needs, so it can start close to the right size. It then tries JPEG quality levels from high to low and keeps the highest quality that fits under your limit. If the photo still has room to spare at high quality, it enlarges the picture a little, because extra pixels usually look better than extra quality. If you set a minimum and the photo is too small to reach it, the picture is enlarged, and as a last step harmless padding bytes are added inside the file so it reaches the minimum without changing a single pixel.
When you set centimetres or inches, the tool converts them to pixels at the DPI you choose (300 DPI if you leave it blank) and writes that DPI into the JPG header, which some portals read. Everything runs in your browser with your device's own image engine, so the photo is never uploaded anywhere.
Tips for a sharp photo at a small size
- Crop before you shrink. A tightly framed face uses the KB budget on what matters. If your form gives pixel dimensions, enter them so nothing is wasted on extra pixels.
- Use a plain, light background. Busy backgrounds take more bytes to store and leave less for your face.
- Start from the original photo. A photo that has been forwarded on WhatsApp several times is already compressed, and shrinking it again shows blocks.
- Use daylight. A dim photo is grainy, and grain is expensive to compress. If your photo is dark, raise Brightness a little.
- Do not aim far below the limit. If the form allows 50 KB, a 48 KB file looks noticeably better than a 15 KB one.
Other sizes and tools
Need a specific size? Use the 20 KB resizer, 50 KB resizer or 100 KB compressor. For the signature box, use the signature resizer, which also whitens the background and handles thumb impressions.
Frequently asked questions
How do I resize a photo to an exact KB size?
Choose your photo, type the maximum size your form allows (for example 50 KB) and the result appears straight away. The tool tries the highest JPEG quality first and only lowers quality or resolution as far as needed to fit, then gives you a JPG to download.
My form says the photo must be between 20 KB and 50 KB. What do I enter?
Enter 50 in Max size and 20 in Min size. The result will stay under 50 KB, and if your photo is very small the tool enlarges it so it does not fall under 20 KB.
Is 1 KB 1000 bytes or 1024 bytes?
Both are used, and application portals do not say which one they check. This tool keeps the file under the maximum counted as 1000 bytes per KB and above the minimum counted as 1024 bytes per KB, so it passes either way.
Is my photo uploaded to a server?
No. Resizing happens inside your browser on your own phone or computer. The image never leaves your device, so it is safe for ID and exam photos.
Why does my resized photo look blurry?
Very low limits such as 10 KB or 20 KB leave little room for detail. If the form also gives pixel dimensions, set them under Dimensions: a 200×230 photo at 20 KB looks much sharper than a full-size photo squeezed to 20 KB.
Do I need to print my name and the date on the photo?
Only if your notification says so. The 2026 UPSC, IBPS, SBI and NTA notices we checked do not ask for it. Some state and older forms do, so read the photo section of your own notice.
Can I resize an iPhone HEIC photo?
Yes. Choose the HEIC file as usual and it is converted to JPG on your device before resizing.
Does this work for signatures too?
Yes, but the signature resizer also cleans the paper to pure white and cuts the empty margins, which forms usually expect.
