How to compress an image to a target size

  1. Upload the image. Any JPG, PNG or WebP — from your phone camera roll or your computer.
  2. Pick the target. Choose 100KB, 200KB, 500KB or 1MB, or type any custom size in KB.
  3. Compress. The tool searches JPEG quality levels — shrinking dimensions only if quality alone cannot reach the target — and keeps the best version that fits.
  4. Download and use it. Save the JPEG and upload it to the portal, form or email that demanded the size.

💡 The short answer: why does JPEG beat PNG for photos?

JPEG, standardized in 1992 by the Joint Photographic Experts Group, compresses photos by discarding detail the human eye barely notices — which is why a 5MB phone photo can become a sharp 200KB JPEG. PNG is lossless and better for logos and screenshots, but for photographs it is often 5–10× larger. That is why this tool outputs JPEG: it is the format that actually reaches small targets without destroying the picture, and every portal on earth accepts it.

Where target-size compression saves the day

🎓 University & job portals

Application portals commonly cap uploads at 200KB. Our university PDF guide covers documents; this tool covers the photo and signature images those same portals demand.

🪪 ID & visa photos

Passport photos, visa uploads and ID scans all come with size caps. Hit the exact number instead of guessing and re-uploading five times.

📧 Email attachments

Some mail servers still reject attachments over 1MB. Shrink the photo once and the email goes through.

🌐 Faster web pages

A 200KB hero image loads in a blink; a 5MB one does not. Compress before publishing and your visitors stay.

📄 Images inside PDFs

Need the image inside a document? Compress it here first, then build the PDF with our JPG to PDF tool — or shrink the whole PDF with compress PDF to target size.

🔒 Photos stay private

Server-based compressors receive your photos. Ours never does — compression runs in your browser's own image engine.

Straight talk: limits

🖼️ Output is always JPEG

JPEG cannot carry transparency — transparent PNG areas become white. For logos or graphics with transparency, keep the PNG and use our general image compressor instead.

📉 Tiny targets soften detail

A detailed photo forced under 50KB will look soft. That is the format's limit, not a bug — pick the largest target the portal allows.

💾 Nothing stored

Because nothing is uploaded, nothing is kept for you either. Download the compressed image before leaving the page.

Compress Image to Target KB FAQ

Is this image compressor really free?

Yes — unlimited images, every target size, forever. No account, no watermark, no payment details.

How do I compress an image to exactly 200KB?

Upload the image, select the 200KB preset (or type any custom size), and hit Compress. The tool searches JPEG quality levels — and shrinks dimensions if needed — until the file lands at or under your target.

What target sizes can I pick?

Presets cover 100KB, 200KB, 500KB and 1MB, plus any custom size you type in KB.

Will compressing ruin my image quality?

The tool picks the highest quality that still hits your target, so quality loss is minimal for reasonable targets. Very small targets on huge photos will soften detail.

Are my photos uploaded anywhere?

No. Compression runs on your device with the browser's canvas engine. Your photos never leave the page.

What formats are supported?

JPG, PNG and WebP uploads. Output is JPEG, the smallest format for photos. Transparent areas become white in the JPEG.

Can I compress an image to under 100KB?

Yes — type any custom target, even 50KB. If the image cannot reach it even at minimum quality, the tool scales the dimensions down and retries.

What happens to my image when I close the page?

It disappears with the tab. Nothing is uploaded or stored anywhere, so download the compressed image before leaving.
