Compress

Tools for reducing image file size to a target KB limit.

Most image compressors make you guess with a quality slider and hope the file lands under the limit. These tools work the other way around: type the KB target a form or portal demands, and the compressor searches across quality levels until the file fits — at the highest visual quality the limit allows. The Image Compressor handles JPG, PNG and WebP in one place; Compress JPEG and Compress PNG are tuned single-format versions of the same engine. And because portals reject undersized files just as strictly as oversized ones, Increase Image Size in KB pads a too-small file up to a minimum requirement without visibly changing it.

Exact-KB compression matters most to Indian exam and government-portal applicants — signature, photo and document uploads routinely specify a hard KB window, and every failed attempt costs time on a deadline. But the same tools serve anyone shrinking photos for email, WhatsApp or a website.

Everything runs in your browser on the Canvas API. Your images never touch a server — no upload wait, no stored copies, and nothing to trust us about, which matters when the file is an ID document, a KYC photo or a signed declaration. Load a tool once and it keeps working even offline.

Frequently asked questions

How do I compress an image to exactly 100KB or 50KB?

Open the Image Compressor, switch to Target Size mode, and type the KB value your form demands. The tool re-encodes the image at successive quality levels until it lands at or just under the target, so you get the best quality that fits without trial and error.

Are my photos uploaded to a server when I compress them?

No. Compression runs entirely in your browser using the Canvas API — image data never crosses the network. You can verify this yourself: load the page, disconnect from the internet, and the tool keeps working.

What if the portal says my file is too small instead of too big?

Many portals enforce a minimum file size as well as a maximum. Use Increase Image Size in KB to pad the file up to the required minimum without visibly changing the image.

Should I compress a PNG or convert it to JPG first?

For photographs, convert to JPG first — PNG is lossless and cannot discard detail, so photos saved as PNG are far heavier than they need to be. Keep PNG for screenshots, logos and graphics with sharp edges or transparency, and shrink those with Compress PNG.
