Compress Image to 100 KB

100 KB is a very common upper limit: application forms use it for handwritten declarations and larger photos, job portals for profile pictures, and many websites and email tools for inline images. This page is preset to 100 KB. Drop your files and each one comes back as a JPG just under 100 KB with as much quality as the limit allows.

Where a 100 KB limit shows up

• Handwritten declarations in bank exam forms (often 50 to 100 KB at 800 × 400 px)
• Photos and scanned ID proofs for passport, visa and admission portals
• Profile photos on job portals and professional networks
• Inline images in emails, newsletters and CMS uploads with a 100 KB limit

How to compress a photo to 100 KB

1. Drop your photos on the upload box, click to choose files, or paste an image with Ctrl+V. The target is already set to 100 KB.
2. For a handwritten declaration or a form with fixed dimensions, set them under Resize → Exact. For a website image, choose Max and enter 1000 px to keep a sensible size.
3. Each image is compressed automatically; the file list shows the new size next to the original.
4. Drag the before/after slider to check the quality. The result line shows the new dimensions, the file size and the JPG quality that was used.
5. Click Download, or Download all (ZIP) when you compressed several images.

What fits in 100 KB

At 100 KB a photo can usually stay at 800 to 1000 px on the long side with excellent quality, which is plenty for any form, a profile picture or an email. A handwritten declaration at 800 × 400 px fits easily because the paper is mostly white. An A4 page scanned at full resolution is harder: crop the margins and expect the tool to scale it to around 1000 to 1200 px wide, which keeps normal-size text readable. For forms stick with JPG; for your own website, WebP at 100 KB gives even more detail.

Behind the scenes the tool does not guess. If your photo is over 100 KB, it runs a quick search for the highest JPG quality (up to 80%) that still lands under the limit, keeping about 1.5% headroom so the portal's own byte count never tips it over. Only when even 35% quality is too big does it scale the width and height down, step by step, and search again. If you set an exact pixel size under Resize, the dimensions are never changed: the quality may go lower instead, and a warning appears if 100 KB cannot be reached at that size.

Tips for the best result at 100 KB

• Write the declaration with a black pen on white paper and photograph it flat, without shadows from your phone.
• Photos straight from a phone are 3 to 5 MB. At 100 KB the tool will reduce them to roughly 1000 px, which still looks sharp on screen.
• Many images for a website? Drop them all at once, then download everything in one ZIP.

Private, free and unlimited

Everything runs in your browser. Your photos are never uploaded, camera and location data (EXIF) are removed from every result, and there is no sign-up, no watermark and no daily limit.

Need exact pixels first? Use the custom image resizer. For stricter limits try compress to 50 KB, or give the image more room with compress to 200 KB.
