How to compress an image to 100KB (or any size)
- Drop your image above — or several at once.
- Pick the size limit you need: 100KB is selected by default, or choose 20KB–1MB, or type a custom limit.
- The tool automatically finds the best quality that fits under the limit. Click Download — the file is guaranteed to be at or below your target.
Why do uploads demand "under 100KB"?
Government portals, visa applications, job sites, school forms and older CMS systems often enforce strict file-size limits — commonly 20KB, 50KB, 100KB or 200KB — to keep their storage and bandwidth predictable. Your phone's photos are typically 3–8 MB, which is 30–80× over the limit. This tool bridges that gap in one step: it repeatedly tests quality levels (and, if needed, dimensions) until your photo fits exactly under the requirement.
Tips for the best result
Choose JPEG for photos — it compresses faces and scenery most efficiently. Use WebP if you need a transparent background and the upload form accepts it. For very small targets like 20KB, a close-up crop of the subject beats a wide shot, since fewer details compress better.
Is it private and safe?
Yes — and for this tool that matters more than usual, because size-limited uploads are often ID photos, passports and application documents. Toolyard does all processing inside your browser on your own device. Your images are never uploaded to any server, so nothing can be stored, seen, or leaked.
Frequently asked questions
Will my image still look good at 100KB?
Usually yes. The tool searches for the highest quality that fits under your limit and only reduces dimensions when quality alone isn't enough. Typical photos remain sharp at 100KB.
What if the target can't be reached?
The tool steps down quality and dimensions automatically. If a target is truly impossible for your image, you'll get the smallest achievable file with a note — no silent failures.
Can I compress to 50KB or 20KB too?
Yes — pick any preset from 20KB to 1MB, or type a custom limit in KB. The same automatic search applies.
Do you store my images?
Never. Files stay on your device and are never sent anywhere — safe for passport and ID photos.
