PDF Size Limits for Document Uploads on Indian Forms (UPSC, IBPS, NTA and More)

The table gathers every PDF figure found in the documents listed under sources. The year column names the notice or bulletin the number was read from, because these limits move between cycles: the RRB Level 1 CEN of 2025 says less than 400 KB while its own FAQ answers 500KB, and the UPSC figure for a photo ID changed when the new candidate portal replaced the OTR screens.

Three bodies dominate searches for this question. UPSC publishes a single sheet, Instructions for uploading documents, with a row for each file: certificates and affidavits are pdf at 50KB–300KB, while the photo, signature and photo ID are jpg. IBPS repeats one block in every CRP notification: the document must be a PDF, on an A4 page, not exceeding 500 KB. NTA writes the same band into the NEET, JEE and CUET bulletins, 50 kb to 300 kb for each scanned certificate.

Every figure in the table is the weight of one finished file, measured after saving, and it applies to each upload field separately. A two-page caste certificate scanned into one PDF still has to come in under 300 KB on NEET or 500 KB on IBPS; the page count changes nothing in the rule, only in how hard the target is to reach. IBPS adds a page-size condition on top, A4, which is about the paper, not the bytes.

Two notices speak about combining documents. The RBI appendix suggests clubbing similar proofs into one scan when a single criterion needs several papers, and says the total must still fall within the 20 KB to 500 KB range. The Income Tax e-Proceedings FAQ works the other way round, with a cap on each attachment and a second cap on all of them together. UPSC goes further than size: each file must carry the exact name from its table, such as board_certificate, or it will not be accepted at all.

A minimum is as binding as the maximum. NEET, JEE, CUET and UPSC all start their bands at 50 kb, the RBI at 20 KB and the e-Visa at 10 KB, so a certificate saved as a very small, blurred PDF can be refused for being light rather than heavy.

File size follows three settings: resolution, colour and the compression quality of the page image. An A4 sheet is 210 × 297 mm, and at 300 DPI in colour its scan is roughly 1 MB to 3 MB as a JPEG, well past every cap in the table. The same sheet at 150 DPI in greyscale comes out at about 150 KB to 400 KB, which already fits most 300 KB and 500 KB fields, and printed text on a certificate stays readable at that density.

The IBPS and RBI notices say the same thing in their own words: if the file is over the limit, adjust the DPI resolution and the number of colours while scanning. Phone scanning apps hide these controls behind a quality or size setting; pick the medium option, choose black and white or greyscale for a printed certificate, and keep colour only where a seal or hologram matters.

Type the portal’s number as a hard maximum and the compressor works through three stages, stopping at the first that fits. It begins by saving the file again in a tighter structure, dropping unused objects and packing the internal tables; nothing visible changes, text stays selectable, and a loosely exported PDF often needs no more than this.

If the file is still over, the second stage re-compresses only the photographs and scans embedded in the pages. Their JPEG quality is lowered in measured steps, each result weighed, and they are scaled down only when quality alone is not enough. Text, lines and form fields are left alone, so a certificate that was scanned as one picture per page shrinks while any typed text stays searchable.

Only when that fails does the third stage render each page as a picture and rebuild the PDF from those pictures at whatever quality and resolution fits. The page keeps its size in centimetres and prints the same, but the text becomes part of the image and can no longer be selected. The result card names the stage used, the page count and the before and after sizes, so you can see which route the file took.

For bands with a floor, switch on the minimum and type it. If the compressed file lands below that number, unused padding data is added inside the file so it sits within the range; the pages themselves are unchanged. A file that is already under the maximum is handed back as it is, since compressing it again would cost quality for nothing.

Photographs, signatures, thumb impressions and handwritten declarations are image fields almost everywhere, with their own much smaller bands. NEET (UG) 2026 asks for the photograph as a JPG/JPEG of 10 kb to 200 kb and the signature at 10 kb to 100 kb; UPSC wants the photo as a jpg of 20KB to 200KB and the signature at 20KB to 100KB; IBPS PO keeps the handwritten declaration and left thumb impression as JPG files. SSC asks for no PDF at all under its 2026 notices, only a 10 to 20 KB JPEG signature, and the SBI PO 2025 advertisement likewise lists only JPG fields.

The photo ID is the field that swaps format between portals. The UPSC upload sheet lists id_card as a jpg of 20KB–200KB, whereas the older OTR FAQ still says the Photo-ID should be in PDF format at 20 KB to 300 KB; NEET takes identity proof as a JPG of 10 kb to 200 kb, and the e-Visa takes the passport bio page as a PDF. Read the field label on the upload screen, and if it says JPG, use the image compressor rather than this one.
