Compress Image to 100KB
Compress JPEG, PNG & WebP to exactly 100KB for job portals, exam forms (SSC, UPSC), and profile uploads. Works for photos and signatures. No upload.
Why compress an image to 100KB
100KB is one of the most common file-size limits on the web. Government job portals, university admission forms, visa applications, and online exam registrations frequently ask for a photo or signature under 100KB. A typical smartphone photo is 2–5MB — way over the limit. KBPress compresses your JPG or PNG to exactly 100KB using local Canvas processing: your image never leaves your browser, you get a precise output in seconds, and there is no sign-up or daily cap.
How to compress an image to 100KB
FAQ
Is my image uploaded to a server?
No. Compression happens locally in your browser with Canvas. Your photos are not uploaded, stored or sent through a queue. You can compress to 100KB without an internet connection after the page loads.
Which formats are supported?
JPG, PNG and WebP are supported up to 100MB per file. For tough size limits like 100KB, PNG may be converted to a smaller photo-friendly format to meet the target.
Will the quality drop when compressing to 100KB?
KBPress searches for the best quality setting first. If 100KB is extremely small for your image, it gradually reduces dimensions so the file can actually fit. For most photos at 100KB, quality loss is barely noticeable.
Do I need to sign up or create an account?
No. KBPress has no sign-up, no login, and no account system. Open the page, compress your image, download it, and leave. No email, no password, no trial period that expires.
How do I compress my photo and signature for an exam form?
Upload your photo, select the required KB size (commonly 20KB or 100KB depending on the exam), and compress. Repeat the same for your signature image. KBPress handles photos and signatures the same way — all locally.
Can I keep my image dimensions (e.g. 800×1000px) while compressing to 100KB?
KBPress tries to preserve your original dimensions. It first lowers the compression quality setting. Only if the target KB is still not reached does it gradually reduce dimensions. For common sizes like 3.5cm×4.5cm passport photos, you may need to crop first, then compress.
What is the difference between compressing and resizing an image?
Compressing reduces file size (KB) by adjusting quality and encoding — the pixel dimensions stay the same. Resizing changes the actual pixel dimensions (width × height). KBPress does both: it compresses first, and only resizes if needed to hit your target KB.
