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.

Why Compress an Image to 100KB?
100 KB (about 0.1 MB) is a common ceiling for resume photos and for the document verification step of many online forms. Job sites like Indeed and LinkedIn are places people upload a profile photo or CV attachment, and smaller company portals tend to be stricter. These portals often set a KB limit, so check the exact number on the form.
The upside is that 100KB gives you real quality. A head-and-shoulders photo for a CV can stay sharp at a decent size, and an ID card or certificate scan keeps fine print readable. A crisp, well-lit photo does more for a first impression than you'd think.
If the job site is stricter, compressing to 50KB still keeps a portrait clean. If it allows more, 200KB gives extra detail for full-page documents.
Supported Image Formats & Technical Considerations
WebP is selected by default because it usually looks a fair bit better than JPG at the same size, so a 100KB WebP is often noticeably crisper. Many job portals and verification forms only accept JPG, though, so check the allowed types next to the upload button and switch if needed.
Dimensions matter for verification. A scan that's been shrunk too far can fail a manual check because someone can't read a number. At 100KB, most single-page scans keep enough pixels, but crop off blank margins so the space goes to the text.
PNG output is possible but rarely worth it for photos. It's lossless, so reaching 100KB means cutting the dimensions hard. Keep PNG for a logo or a simple diagram.
Tips for Compressing a Resume Photo to 100KB
- Use a recent photo with a plain background and soft light from the front.
- Crop to head and shoulders before compressing. Nobody reviewing your CV needs to see the room behind you.
- Pick JPG if the job site doesn't mention WebP. Every system takes it.
- For ID or certificate scans, keep all four corners in the frame. Some checks reject documents with cut-off edges.
- Rename the download to something sensible like yourname-photo.jpg before you upload it.

Frequently Asked Questions
Can I compress a JPG to 100 KB?
Yes. Set the output to JPG if you need a .jpg file. If the site takes WebP, that gives a little more quality at the same size.
Will a 100 KB photo look good on my resume?
Yes. For the small photo most CVs use, 100 KB is plenty to look sharp on screen.
How long does it take?
A second or two, normally. Big photos on older devices can take a bit longer, because all the work happens on your own device. Nothing is uploaded to a server, so your CV photo stays with you.
How do I reduce an image from MB to 100 KB?
Pick your photo, choose 100 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 100 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 my image uploaded anywhere?
No. The compression happens inside your browser, on your own phone or computer. Your image is never uploaded to a server, so it isn't sent across borders or stored by anyone, including us.
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.
