Image & Signature Requirements for Indian Online Forms
Many government exams, portal registrations and online application forms in India set strict file size limits for photos and signatures, usually under 20 KB, 50 KB or 100 KB. BundleFlow compresses your photo locally in your browser, so it never leaves your device, and gets it under the limit with the best quality that size allows.
| Exam / Portal | Photograph Size | Signature Size | Format |
|---|---|---|---|
| SSC (CGL, CHSL, MTS, GD) | 20 KB - 50 KB | 10 KB - 20 KB | JPG / JPEG |
| UPSC (Civil Services, NDA, CDS) | 20 KB - 300 KB | 20 KB - 300 KB | JPG / JPEG |
| IBPS / SBI Bank Exams | 20 KB - 50 KB | 10 KB - 20 KB | JPG / JPEG |
| NEET / JEE Main (NTA) | 10 KB - 200 KB | 4 KB - 30 KB | JPG / JPEG |
Typical limits, last checked October 2026. Portals can change sizes, formats and pixel dimensions with each notification, so always confirm in the official notice before you upload.
Compress Signature & Passport Photos for Government Exams
Filling out an online application for SSC (CGL, CHSL, GD, MTS), the Railway Recruitment Board (RRB NTPC, Group D), UPSC, IBPS Bank PO/Clerk or NTA NEET/JEE? These portals reject a passport photo, signature or thumb impression that's over their size limit, often 10 KB or 20 KB. Check the notice for the exact number.
Choose that size here and the tool brings your scanned signature, thumb impression or passport photo to it or just under, keeping the ink and your face as clear as the limit allows. Your documents stay on your device. Nothing is uploaded to a server.

Why Compress an Image to 20KB?
Use this as a JPG photo resizer to 20KB for forms that require that limit. For dedicated exam presets, use the SSC Photo Resizer, SSC Signature Resizer, or IBPS Photo and Signature Resizer. Requirements vary, so check your application. For thumb impressions, crop the relevant area with the Image Cropper first.
The good news is that 20KB is enough for a clear head-and-shoulders photo, as long as your face fills most of the frame. A wide shot with your face as a tiny dot in the middle won't hold up. Text and signatures stay legible at this size too, if the scan is clean. To crop and compress an image to 20KB online, crop first with the Image Cropper and then compress it here.
Keep in mind that size is only one of the rules. Many forms also specify dimensions, background colour or how much of the frame your face should fill, so read the instructions on the form itself. This browser-based image compressor works on your device once loaded; it is not a guarantee that the whole site works offline. If your limit is tighter, compress to 10KB instead. If you're allowed more room, 50KB gives noticeably more detail.
Supported Image Formats & Technical Considerations
For a passport-size photo, JPG is the usual requirement, so it's already selected. WebP holds a little more detail at 20KB, but plenty of older forms reject it, so only switch if the form lists it. Crop to portrait proportions with the Image Cropper, or use the SSC Photo Resizer for its size presets.
Here's what happens when you press the button. The tool first tries to keep your photo's dimensions and lowers only the quality. If that would leave visible blocks around the eyes and hairline, it reduces the dimensions instead and tries again. A slightly smaller, clean photo almost always looks better than a big, smudgy one.
Signatures behave differently from photos. They're mostly white with thin dark lines, which compresses very well, so a signature at 20KB can often keep more pixels than a portrait at the same size. Either way, the work happens in your browser and your photo is never uploaded to a server.
Tips for Compressing a Photo to 20KB
- Stand against a plain, light wall. A busy background steals bytes from your face.
- Use soft, even light from the front. Harsh shadows and low-light grain make the file bigger and the face murkier.
- Crop so your head and shoulders fill the frame before you compress.
- If the form gives exact pixel dimensions, crop to that shape first, then compress. The cropper sets a crop shape, not physical centimetre dimensions; check the final pixel requirements with your form.
- If it asks for a range like 10 to 20 KB, choose 20 KB. You'll land just under the top.

Frequently Asked Questions
How do I compress an image to 20 KB for official government forms?
Upload your photo or signature, choose 20 KB and click Compress Image. The tool finds the highest quality that fits under 20 KB, only shrinks the dimensions if it has to, and tells you plainly if 20 KB can't be reached. Check the exact size, format and pixel dimensions in your form's notice, because portals like SSC or UPSC can change them.
Is this image compressor suitable for SSC, Railway (RRB) and UPSC exam forms?
Yes. Application portals for SSC (CGL, CHSL, GD Constable), the Railway Recruitment Board (RRB NTPC, Group D, ALP), UPSC Civil Services, IBPS and NTA (NEET, JEE) all set strict KB limits for photos, signatures and thumb impressions. The limits differ between exams and can change with each notice, so check the official notification, then pick that size here. The tool brings your file to that limit or just under it, right in your browser.
Will my photo still look okay at 20 KB?
For a cropped portrait or a document, usually yes. A wide, detailed photo will come out smaller and a bit soft.
My form says the photo must be between 10 KB and 20 KB. What do I pick?
Pick 20 KB. The tool goes for the best quality at or under 20 KB, so you'll normally land just below the limit, which sits inside that range.
Can I compress a signature to 20 KB?
Yes, and it's easier than a photo. Signatures are mostly white space, so they shrink well. Crop close to the ink, keep JPG selected and choose 20 KB.
How to compress PAN card signature under 20KB?
Choose a JPEG output and a target at or below the limit stated by your PAN application. This page offers a 20 KB target, but PAN application requirements vary and the tool does not set exact pixel dimensions. Check the current PAN portal instructions before submitting.
How do I reduce an image from MB to 20 KB?
Pick your photo, choose 20 KB and tap Compress Image. The tool lowers the quality a little at a time until the file fits, and only shrinks the dimensions if it has to. A 4 MB phone photo normally takes a few seconds.
Can I compress a photo to 20 KB without losing quality?
Honestly, not completely. When a file gets a lot smaller, something has to give. But the tool always picks the highest quality that still fits your target, so you lose as little as possible. At sensible targets most people can't spot the difference on a phone screen.
Is it safe to compress private photos and signatures here?
Yes. Everything happens inside your browser, on your own device. Your photo or signature is never uploaded to a server, so nobody else sees or stores it.
Can I convert WebP or PNG photos to JPG format for form submission?
Yes. Most Indian exam portals (SSC, UPSC, NTA) ask for JPG/JPEG. Upload your WebP or PNG photo, choose JPG as the output format, and you'll download a compressed .jpg. HEIC photos from iPhones aren't supported yet. On the iPhone, go to Settings > Camera > Formats and choose Most Compatible to take photos as JPG, or share the photo by email or chat, which usually converts it to JPG.
Can I compress multiple images at once?
Not yet, it's one image at a time for now. Once you've downloaded a result, tap “Compress Another Image” and pick the next photo. Bulk compression is on our list.
