If even low quality is too big, it reduces the dimensions step by step and tries again. Sizes count 1 KB as 1,000 bytes, slightly stricter than 1,024, so the file fits either way.

Add your file and download the result. Step 1 Leave "Under 100 KB" selected. If the form lists dimensions, enter them under Exact size. Step 2 Drop, paste or choose your photo or scanned document. Step 3 Check the final size shown against 100 KB, then download it. ## Tips for Getting Under 100 KB 100 KB is roomy for a passport-style photo but tight for a full-page scan. These keep the result clear. ### Crop to What Matters Trim empty margins around a document or extra background around a face. Fewer pixels leave more room for detail. ### Scan Flat, in Good Light A flat page in even, bright light compresses far better than one with shadows and creases. ### Match the Requested Size If the form gives dimensions, set them under Exact size so you meet both rules in one go. ## Private, Free and Quick Your photo or document is compressed in your browser and never uploaded. ### Nothing Uploaded Files stay on your device. A decoder for formats like HEIC is fetched from dragbin.com only if your browser needs it. ### Best Quality Under 100 KB The highest quality that fits is chosen for you, so the image isn't squeezed more than needed. ### Several Files at Once Add a photo and a few scans together and download them as one zip. ## Try DragBin Today Pair private, in-browser file tools with zero-knowledge, quantum-resistant cloud storage. 5GB free, forever.

Portals that take large numbers of applications keep files small so storage and page loads stay manageable, and 100 KB is a common cap for photos and scanned documents. Limits, dimensions and accepted formats differ from site to site, so check what your form lists. ### Will my photo or scan still look good at 100 KB? Usually, yes. A passport-style photo or a cropped ID scan stays clear well under 100 KB. The tool picks the highest quality that fits and only reduces the dimensions if quality alone isn't enough. ### Is 100 KB here the same as 100 KB on the website? The tool counts 1 KB as 1,000 bytes, so under 100 KB means at most 100,000 bytes. That also passes on a site that counts 1 KB as 1,024 bytes, where the limit would be 102,400 bytes. ### The form also has a minimum size. Will the file meet it? Often, because the tool keeps the highest quality under 100 KB, which tends to land close to the limit. A small image may still come out well below it. If that happens, enter larger dimensions with the exact size option and compress again. ### Are my documents uploaded to DragBin? No. Compression happens in your browser. For HEIC photos outside Safari, or WebP output in Safari, the page downloads the needed decoder or encoder from dragbin.com, but your files themselves never leave your device.
