About the Compress to Specific KB/MB
Government portals, job sites and exam application forms often reject photos above a strict limit such as 20 KB, 50 KB or 100 KB. Instead of guessing quality settings, type the size you need and this tool searches for the highest quality that fits under it, then gives you the file. It is the fastest way to resize a photo or signature to an exact KB size for passport, visa, SSC, UPSC, NTS or university applications.

Frequently Asked Questions
How do I compress a photo to 20 KB or 50 KB?
Upload the photo, type 20 (or 50) in the Target Size box and click Compress. The tool tries different quality levels automatically and returns the best-looking version that is at or under your limit.
How do I reduce a photo to 100 KB for an online form?
Enter 100 as the target size and upload your photo. If the form also asks for specific dimensions, resize first with Resize Image by Pixels, then compress to 100 KB.
How accurate is the target size?
The result normally lands within a few KB below your target. It never deliberately goes over, because forms reject files that are even slightly too big.
Can I compress an image to 1 MB or 2 MB?
Yes — enter the size in KB (1 MB = 1024 KB, so type 1024 or 2048). This is handy for email attachments and upload portals with megabyte limits.
Why can’t my image get down to the size I asked for?
A very large photo may not fit into a tiny target such as 10 KB without reducing its dimensions. Resize it to a smaller width first (for example 600 px), then compress again.
How do I compress a signature image to 10–20 KB?
Crop the signature tightly, resize it to around 300–400 px wide, then set the target to 10 or 20 KB here. Signatures have few details, so they stay readable even at very small sizes.
Will the photo look blurry after compressing to a small size?
Small targets mean lower quality, but the tool always picks the highest quality that fits. Passport-style photos usually look fine at 20–50 KB.
What is the difference between KB and kb?
KB (kilobyte) is file size; 1 KB is 1,024 bytes. Upload forms almost always mean KB, which is what this tool uses.
Does it change my photo’s format?
No. The output stays in the same format as your upload, so a JPG stays a JPG — the format most application forms require.
Does the Compress to Specific KB/MB tool store my photo?
No. Your photo is processed in memory for this request only and deleted immediately — important when you are uploading ID photos and signatures.
