A form that wants a photo between 20 KB and 50 KB is running two checks, and most advice only covers the upper one. A phone picture of several megabytes plainly fails at the top. The surprise comes at the bottom: a portrait cut to the small pixel size these forms prefer and saved in the usual way often weighs well under 20KB, and it is turned away for being too light. The IBPS notice for RRB recruitment warns that the application will not move to its next stage until the photo and signature meet the stated specifications, so a miss at either end holds you up.
Both limits are already set on this page, 50 in the maximum box and 20 in the minimum. A heavy file is brought down by lowering JPG quality and, only if that falls short, the pixel count. A light one goes the other way: quality is raised towards the top first, and the picture is enlarged only as a last resort. The result card says “Within your 20 KB – 50 KB range” once the file fits.
How to use it
- When the notice gives pixels, such as 200 x 230, create that size first in the resize tool with “Crop to fill” selected. A phone portrait loses a thin band from the top and bottom, so keep some space above the head.
- Add the resized file here, or the untouched photo if the form names no pixel size. HEIC and PNG pictures work as well and are saved as JPG.
- On the result card, check two things: the weight is inside the band, and the width and height are still the ones you created.
- If the dimensions grew, the picture was too plain to reach 20KB at that size. The first section below explains why and what to change.
Why a correctly sized photo can weigh too little
200 × 230 is only 46,000 pixels, and a JPG that small has little to store. Five photos of people, cropped to it and saved at quality 92 out of 100, weighed between about 11KB and 23KB, and four of the five were below the floor. Saving the same pixels at the top quality setting lifted all five into the band, at roughly 20KB to 38KB, without changing the width or height. That is the first thing this page tries.
The closest call in that test was the most form-like picture: a man against a plain light wall, which cleared 20KB by about half a kilobyte. A pale, even background is what the notices ask for, and it is also what makes a file light, because flat areas cost almost nothing to encode. When top quality still falls short, the tool enlarges the picture, by up to three times, until it passes 20KB, and the card then shows a bigger width and height than you made. The notices write “preferred” after 200 x 230 pixels and give the file size as a range. If you would rather keep the exact pixels, retake the photo in good light without a smoothing filter and frame it closer, so the face fills more of the picture and gives the encoder more to hold.
Notices that use the 20 KB to 50 KB band
Photograph at 200 x 230 pixels (preferred), 20 KB to 50 KB: IBPS for its PO/MT, CSA, SO and RRB recruitment, SBI for Probationary Officers and Junior Associates, RBI Services Board, and NABARD for Assistant Manager Grade A, each with 4.5cm × 3.5cm and JPG/JPEG written alongside. The RBI Office Attendant recruitment hosted by IBPS and the MIDC recruitment portal give the same band and 200 x 230 pixels without the word preferred. The IBPS, SBI, RBI and NABARD forms also have you capture a live photo with a webcam or phone in addition to the uploaded file; that one is taken inside the form and needs no resizing.
Left thumb impression, in the same band: IBPS, SBI, NABARD and MIDC ask for 240 x 240 pixels in 200 DPI, equal to 3 cm by 3 cm, from a print made in black or blue ink on white paper. This page stores no DPI value, so if you want 200 written into the file, run the finished JPG through the DPI tool, which edits that number and leaves the pixels alone.
TNPSC, for its Group II and IIA notification: photograph 20 KB to 50 KB, stated as 4.5 cm height x 3.5 cm width (170 pixels x 130 pixels) at 200 DPI, with the applicant’s name and the date of photography printed at the bottom. The pixels follow the same order as the centimetres, so the picture is 130 wide and 170 tall. A portrait that small normally saves under 20KB, which is exactly when the preset minimum earns its place. Name and date cannot be added here; they must already be on the photo.
Frequently asked questions
- What pixel size goes with a 20KB to 50KB photo?
- The band says nothing about pixels by itself; that part comes from the notice. The bank recruitment forms listed above pair it with 200 x 230 pixels, and TNPSC with 130 wide by 170 tall. When no size is given, a phone photo added straight to this page usually comes back at roughly 1,000 to 1,500 pixels on its longer side, close to the 50KB cap, which is plenty for a passport-size print.
- Is 200 x 230 pixels the same shape as 4.5 × 3.5 cm?
- Not exactly. 200 by 230 is squarer: its width is about 87 percent of its height, against about 78 percent for 3.5 by 4.5 cm. The pixel figure is the one you can make directly, since a file has no centimetres until a DPI is attached. Cropping a passport-shaped photo to 200 × 230 trims a little from the top and bottom, which is why the steps above suggest leaving room over the head.
- The portal says my file is too large, but the card shows it under 50KB. Why?
- This page counts 1KB as 1,024 bytes, so the cap is 51,200 bytes and the floor 20,480. A portal that counts in thousands stops at 50,000 bytes, and a photo taken straight from the camera can land just above that here. Type 48 in the maximum box and run it again; the floor needs no change, because 20,480 bytes already clears 20,000.
- Can I download the result as a PDF?
- No, the result is always a JPG, which is the format the photo and thumb impression fields in these notices ask for. In the IBPS notices a PDF is used for certificates, of up to 500 KB, and those go into a separate field of their own.
- Is 20KB to 50KB the SSC photo size?
- Not in the current notices. Charts that give SSC a 20 to 50KB photo describe the older process; Staff Selection Commission forms now take your picture through the device camera during the application, so there is no photo file to prepare. The one image SSC asks you to upload is the signature, at 10 to 20 KB.
- The same form wants my signature at 10 to 20 KB. Can I do that here?
- Yes. Change the maximum box to 20 and the minimum to 10, then add the signature scan, or open the signature page in the links below, which starts with that band already set. Prepare the photo and the signature as two separate files, since each has its own upload field.
