About this tool
A 100KB limit gives noticeably more breathing room than the tighter 20KB and 50KB caps, making it a common choice for email attachment limits, web banner images, and portals that want a higher-quality photo than a bare ID shot — for example, profile photos on job sites that display the image larger, or scanned documents where fine print needs to stay sharp. This tool is tuned for that 100KB target, preserving noticeably more detail and color depth than the stricter presets while still keeping file sizes small enough to attach to emails or load quickly on a web page. Simply upload a high-resolution JPG, PNG, or WEBP photo and the tool automatically downscales and compresses it to fit the 100KB ceiling with minimal visible quality loss. All processing happens locally in your browser.

Tips & common mistakes
- •Since 100KB allows more quality headroom than 20KB/50KB, this is a good choice for banner images meant to be viewed larger on screen rather than thumbnail-sized photo uploads.
- •If your email provider has its own attachment compression, your final sent file size may differ slightly from what you download here — test with a real send if the limit is critical.
- •Very large camera photos (10MB+) will still be downscaled to reach 100KB; for the best balance of sharpness and size, start from a moderately sized original rather than a full-resolution DSLR photo.
- •If you need the image for a webpage, consider whether WEBP export elsewhere might compress smaller at the same visual quality — this tool's output is standard JPEG for maximum compatibility.
