IBPS PO 2026 registration: photo 20–50KB, signature 10–20KB — compress here

If you are struggling to upload your files due to the strict IBPS PO photo size limit compress rules on the official IBPS exam portal (ibps.in), we can help. The official notification mandates that your passport photo must be between 20KB and 50KB, while your signature must be between 10KB and 20KB. You can easily resize and compress PDF for IBPS PO using Siliph's free online tool to guarantee your documents match these strict size specifications perfectly without losing legibility.

Who needs this guide

Every year, hundreds of thousands of banking aspirants across India face severe technical bottlenecks while filling out their IBPS PO application forms. From my years of helping candidates troubleshoot these forms, the most common roadblock is the strict document upload window. Candidates, especially those applying from rural or semi-urban areas without high-speed broadband or access to advanced image-editing software, rely on mobile camera captures. A standard smartphone photo of a passport photograph or a signature on white paper easily ranges from 2MB to 6MB.

When you try to upload these high-resolution images directly to the IBPS portal, the system immediately throws error messages such as "File size exceeds limit" or "Invalid document dimensions." This happens because the server hosting the recruitment gateway is optimized to accept only specific file volumes to prevent server crashes. If you are a banking aspirant trying to lock in your application before the registration deadline, this step-by-step guide is designed to help you prepare, resize, and compress your images and documents to meet the exact IBPS specifications without losing clarity.

government / exam portal upload requirements

The Institute of Banking Personnel Selection (IBPS) enforces highly specific dimensional and size guidelines for registration documents. While the primary candidates' photos and signatures must be uploaded in JPEG/JPG formats, other supporting documents like caste certificates, EWS certificates, or disability proofs are often required in PDF format. Failing to meet even one of these parameters will block your form submission.

Here is a thorough breakdown of the typical upload requirements for the 2026 IBPS PO registration cycle:

Fix common portal errors

Even after compressing your files, you might encounter technical glitches on the IBPS gateway. Here is how you can resolve the most common issues based on real applicant scenarios.

File too large

If the portal rejects your file claiming it exceeds the permissible size, it is usually because the file size sits exactly on the upper limit (e.g., exactly 50.1 KB for a photo). Our readers often report that keeping files slightly below the ceiling—such as 40 KB for photos and 15 KB for signatures—completely bypasses this error. Re-run your file through the Siliph compressor and set a slightly lower target threshold.

Blurry scan rejected

An automated script on the IBPS portal checks the clarity of facial features and signature lines. If you over-compress a file using low-quality online tools, the image becomes pixelated, resulting in rejection or, worse, application disqualification later. To avoid this, keep your scan DPI at exactly 150 or 200 DPI during compression. Siliph's advanced compression algorithms compress the metadata and redundant color channels while keeping your signature's line edges clean and sharp.

Wrong format

Many candidates make the mistake of manually changing a file's extension from ".png" to ".jpg" by simply renaming the file. This does not change the internal encoding of the file, and the IBPS portal will instantly reject it as an unsupported format. Always use an actual format converter or the Siliph compression engine to process your PNG captures into genuine JPG/JPEG containers.

Upload timeout

During peak application hours, the IBPS servers face heavy traffic, causing connection drops. If the portal throws a generic gateway timeout error, try compressing the scan further to 140KB for PDF certificates, or compress your signature to about 12KB. Smaller files require fewer network packets to upload, making them highly resilient against slow internet connections or high-traffic server delays.

FAQ

What should I do if my hand-written declaration file size is over 100KB?

If your hand-written declaration scan exceeds the 100KB limit, you must compress it before uploading to the IBPS PO portal. Upload the JPG file to the Siliph resizer, set your target output size to approximately 70KB, and download the compressed version. Ensure that the handwritten text remains fully readable on a standard mobile screen before uploading.

Can I sign in capital letters for the IBPS PO registration portal?

No, signatures in capital or block letters are strictly not accepted by the IBPS. If you upload a signature written in capital letters, your registration may be rejected. You must sign in running handwriting using a black ink pen on white paper, scan it, and compress it to the mandatory 10–20KB range.

Why does the IBPS portal say "Invalid Dimensions" when my photo is under 50KB?

The IBPS portal checks both file weight (KB) and pixel dimensions. Even if your photo is 35KB, it will be rejected if the pixel dimensions are not set to the required 200 x 230 pixels. Use our dedicated resizer tool to adjust both the pixel dimensions and file size simultaneously before attempting to upload.

Can I upload my category certificate as a JPG file on the IBPS portal?

No, supporting documents such as caste certificates, EWS certificates, and physical disability certificates must be uploaded strictly in PDF format. The file size of these PDFs must be between 100KB and 500KB. You can use our PDF compression tool to reduce large scanned PDFs down to a safe size of 300KB.

Is there a specific ink color required for the left thumb impression?

Yes, you must use either blue or black ink for your left thumb impression on white paper. Ensure the thumbprint is clear with no smudges, scan it, and compress the file to fit within the 20KB to 50KB limit required by the IBPS exam portal.
