How to Compress an Image to a Specific Size
Upload your photo using the box above, type your target size in KB (for example, 100), choose your output format, and click Convert. The tool searches for the highest image quality that still fits under your limit, then lets you download the result instantly — no software installation needed.
Compress Image to 100 KB
A 100KB limit is one of the most common upload requirements online. Government ID document scans, such as Aadhaar cards, are usually capped around 100KB because legible text matters more than fine photographic detail, and many visa or certificate uploads sit in a similar 150–200KB range. Enter “100” in the target size field, and the tool will get your image as close to that limit as possible without making it blurry.
Compress Image to 50 KB
50KB is the classic passport-photo limit used across major competitive exams and government portals. It’s specifically the standard size for passport-style photos on exams like SSC, UPSC, and IBPS — these portals set tight limits because they need to process millions of photo uploads during short registration windows without overloading their servers. This tool hits that 50KB target automatically, so you don’t have to guess with a manual quality slider.
Compress Image to 20 KB
A 20KB limit almost always applies to signature scans rather than photos. Signature uploads are one of the main reasons portals ask for files this small, while a slightly larger 30KB allowance is typically reserved for thumb impressions or biometric scans. Because compressing to such a small size requires more aggressive quality reduction, this tool balances sharpness and size automatically so your signature still stays legible.
Compress JPG or PNG to Any Custom Size
Need something other than 50KB, 100KB, or 20KB — like 200KB, 300KB, or even 10KB? Just type your exact number into the “Target size” field. The tool supports custom targets across a wide range, making it useful for almost any form, job portal, or admissions system with its own specific upload rule.
JPG vs PNG vs WebP: Which Format Should You Use?
- JPG — best for photographs; smaller file size, minor quality loss, no transparency support. This is also the format almost every exam and government portal expects, since it compresses far more predictably to a target size than PNG.
- PNG — best for logos, graphics, and screenshots; lossless and supports transparency, but produces much larger files for photos.
- WebP — a modern format built for the web; smaller than both JPG and PNG at similar visual quality, but not accepted by most official upload forms.
If a form or portal is asking for your photo, stick with JPG. If you’re optimizing images for your own website, WebP is the better choice.
Why Convert Images to WebP?
At matched visual quality, WebP images typically come out 25 to 34% smaller than JPEG, and lossless WebP averages about 26% smaller than PNG — and since images remain the largest share of bytes transferred on most websites, choosing WebP moves page-load speed more than almost any other single change you can make. Faster-loading images also help with Google’s Core Web Vitals, which can support your search rankings. blazingcdnblazingcdn
Is This Image Converter Safe to Use?
Yes. This tool runs entirely inside your browser — your images are never uploaded to any server. Compression and format conversion both happen locally on your device, so your files stay completely private.
Frequently Asked Questions
Can I convert multiple images at once?
Yes, you can upload several images together and download them individually or as a single ZIP file.
Does this tool reduce image quality?
Only if you set a target file size — the tool then compresses the image as close to that size as possible. Without a target size, it converts at high quality.
Is my image uploaded to a server?
No, all conversion happens locally in your browser — your images never leave your device.
What image formats are supported?
JPG, PNG, and WebP — in any direction.
How do I compress a photo to exactly 50KB?
Upload your photo, type “50” into the Target Size (KB) field, choose your output format, and click Convert. The tool will compress the image as close to 50KB as possible.
Why do exam and government portals ask for photos under 100KB or 50KB?
These systems process huge numbers of uploads during short registration windows, so small, predictable file sizes keep their servers from getting overloaded — which is why JPG at a fixed KB limit is almost always required over PNG.
Why is 20KB usually for signatures and not photos?
A 20KB limit doesn’t leave much room for detail, which is fine for a simple black-and-white signature scan but too small for a clear passport-style photo — that’s why most portals reserve the 20KB tier specifically for signatures or thumb impressions.
