Photo, signature and PDF tools for Indian exam forms

Exam forms reject files that are a few pixels or a few KB off. ExamKit crops and resizes your photo, signature, thumb impression, declaration and PDFs to the numbers in the official notice — on your own phone or computer.

Tools

• Photo resizer

  Crop to the right shape, set exact pixels (for example 200 × 230), and land inside a KB range such as 20-50 KB. Shows the final size in KB and bytes.

• Signature, thumb & declaration

  Trims white margins, turns grey paper white, darkens faint ink and sizes the file. Tabs for signature, thumb impression and handwritten declaration.

• Images to PDF

  Turn phone photos of certificates into one A4 PDF, in the order you choose, and keep it under a limit like 500 KB or inside 50-300 KB.

• PDF size reducer

  Bring a PDF under 100, 200, 300 or 500 KB by turning each page into a compact picture. The PDF is processed on your device, not uploaded.

• Age calculator

  Your exact age on the cut-off date in years, months and days, and whether your date of birth is inside the window printed in the notice.

• Photo and signature joiner

  Join a photo and signature into one JPG for application forms. Choose layout, pixels and maximum KB; both images stay in your browser with no upload.

• Plain white or light background helper

  Make a plain photo background white or light grey in your browser. Adjust corner and colour tolerance, preview edges, and save a JPG under your KB limit.

• Crop photo by cm or inch at DPI

  Crop a photo to editable cm or inch dimensions and DPI, including a 3.5 × 4.5 cm example. Set a maximum KB and download a JPG without uploading your photo.

• Change JPEG DPI without resizing

  Change a JPEG density tag to your chosen DPI without resizing or recompressing the image. Inspect the result locally; nothing is uploaded to a server.

• Convert PNG or WebP to JPG

  Convert PNG, WebP or JPEG images to a JPG under an editable KB limit. Transparent areas become white and processing stays entirely inside your browser.

• Rotate or flip an image

  Rotate an image by 90, 180 or 270 degrees, optionally mirror it, and save a JPG under your chosen KB limit. Free browser processing with no file uploads.

• Check image size, pixels and JPEG DPI

  Check an image’s exact byte size, KB, encoded pixel dimensions and JPEG DPI tag locally. Compare the results with your exam or government form notice.

Upload rules by exam

Each exam page lists the photo, signature and document rules copied from the latest official notice, with a link to the PDF, the page or paragraph, and the date we last checked it. One click opens the tool with those settings.

• SSC CGL, CHSL, MTS Verified
• RRB NTPC, Group D Partly verified
• IBPS PO, Clerk Verified
• SBI PO, Clerk Verified
• UPSC Civil Services Partly verified
• NEET UG Verified
• JEE Main Verified
• CUET UG Verified
• India Post GDS Verified

SSC and RRB no longer take an uploaded photo. Their forms capture a live photo with your camera, so you only need a signature file. See the SSC rules.

How it works

1. Pick your exam, or type in the size from your notice.
2. Choose your photo, signature or PDF. It is opened inside your browser, not sent anywhere.
3. Download the result and compare it with the notice before you upload it to the exam form.

Why you can trust the numbers

• Every rule links to the official notice, with the page or paragraph, and a “last checked” date.
• When we could not confirm a rule from an official source, the page says not verified instead of guessing.
• When official documents contradict each other, we show both and aim for a file that satisfies both.
• File sizes are measured, not estimated. “KB” can mean 1000 or 1024 bytes, so the tools aim for a size that passes either way.

ExamKit is not affiliated with SSC, RRB, IBPS, SBI, UPSC, NTA, India Post or any government body. Always check the official notice.
