Compress Image to 50KB
Get a photo under 50 KB, or inside a 20–50 KB range, at the exact size your form asks for, such as a 3.5 × 4.5 cm passport size photo.
or drop it here, or paste with Ctrl+V. JPG, PNG, WebP or HEIC (iPhone).
How to compress an image to 50 KB
- Choose, drop or paste your photo. JPG, PNG, WebP and iPhone HEIC all work.
- The page opens set for a passport size photo: 3.5 × 4.5 cm at 200 DPI (276 × 354 pixels) and a 50 KB maximum. If the form gives a range such as 20 KB to 50 KB, click 20–50 KB so the file does not end up too small.
- If the form gives other dimensions, change them in centimetres or switch to pixels. If it gives no dimensions, choose “Original”: the tool then keeps the quality at 70 or above and tells you if it had to make the picture smaller.
- Check the preview, the byte count and the dimensions, then download the JPG.
Passport size photo under 50 KB
“Passport size” on Indian application forms usually means 3.5 cm wide and 4.5 cm tall. An image file has no size in centimetres until you choose a DPI, so convert it first: at 200 DPI that is 276 × 354 pixels, and at 300 DPI it is 413 × 531 pixels. At 200 DPI a photo usually fits under 50 KB at close to full quality; at 300 DPI there are twice as many pixels, so the quality may come down a little. The result shows the quality it used.
- Dimensions already show 3.5 and 4.5 cm. Keep 200 DPI unless your form names a different DPI.
- If your photo is a different shape, keep “Crop to fill” so the centre of the photo fills the frame, or choose “Fit with white edges” to keep everything.
- Click 20–50 KB if the form has a minimum, or keep the 50 KB maximum.
For the photo itself: a plain white or light background, your face straight to the camera and well lit, and no caps or dark glasses. A plain background also leaves more of the 50 KB for your face.
Forms that use 50 KB
Two examples, checked against the official documents on 5 October 2026:
| Form | Document | File size | Size |
|---|---|---|---|
| IBPS PO/MT-XV (2025) | Photograph | 20–50 KB | 200 × 230 pixels (preferred), 4.5 × 3.5 cm |
| IBPS PO/MT-XV (2025) | Left thumb impression | 20–50 KB | 240 × 240 pixels at 200 DPI |
| PAN card (Protean online application) | Photograph | up to 50 KB | 3.5 cm tall × 2.5 cm wide, JPG |
| PAN card (Protean online application) | Signature | up to 50 KB | 2 cm tall × 4.5 cm wide, JPG |
Sources: the IBPS notice “Guidelines for scanning and Upload of Documents”, and Protean’s guide to applying for a PAN card online, which also mentions 200 dpi. Rules change between years, so check the notice for your own application.
When 50 KB is not reachable
With “Keep original exactly”, a 12-megapixel phone photo usually cannot go under 50 KB even at the lowest quality, because it has about 12 million pixels to store. The tool says so and shows the smallest it could reach. Set the dimensions your form needs, or switch back to “Original” and let it make the picture smaller.
If your file is under the form’s minimum instead, see increase image size in KB. For other limits, such as 20 KB or 100 KB, use the main reduce image size in KB tool.
Frequently Asked Questions
Is 50 KB counted as 50,000 or 51,200 bytes?
Forms rarely say. This tool keeps the file at or under 50,000 bytes, which is under 50 KB both ways. The result shows the exact byte count, so you can compare it with what your computer or the form displays.
How many pixels is a 3.5 × 4.5 cm passport size photo?
It depends on the DPI. At 200 DPI, which many scanning guidelines ask for, it is 276 × 354 pixels; at 300 DPI it is 413 × 531 pixels. This page opens with 3.5 × 4.5 cm already set; change the DPI if your form names one.
Why did my photo get smaller in pixels?
Only if you left Dimensions on “Original” and the photo could not fit under 50 KB at quality 70 or above. A 12-megapixel phone photo usually cannot. The result tells you the new width and height. If your form needs a specific size, set it, and the tool will keep exactly that size and change only the quality.
Can I compress a PNG to 50 KB?
Yes, but PNG has no quality setting, so the only way to make it smaller is fewer pixels. Choose JPG under “Save as” unless the form insists on PNG; a JPG keeps much more of the picture at 50 KB.
The form says 20 KB to 50 KB. Will a 50 KB limit be enough?
Click the 20–50 KB range instead. Then the file also stays above 20 KB; if a small photo is under 20 KB even at the best quality, blank data is added inside the file without changing the picture.
