Set an exact KB limit and compress images with predictable output while keeping important details readable.
Drag & drop or click to select your image (Max 20MB)
Supports JPG, PNG, GIF, WebP formats
Hit strict upload limits quickly with clear previews and reliable size control.
Set a specific KB ceiling for forms, forums, or email attachments. The tool adjusts quality and dimensions to land close to your limit without manual trial and error.
Edge-focused compression keeps icons, UI labels, and line art readable at small sizes. High-contrast details remain crisp even when the file is heavily reduced.
The size estimate updates as you change width, height, or format, so you can converge on the KB target in one smooth workflow instead of multiple exports.
Choose JPG or WebP to reach the KB target faster. WebP often saves more bytes, while JPG stays compatible with legacy systems and editors.
Lock proportions to prevent stretching, then downscale only if needed. This keeps the image natural while trimming bytes for strict KB limits.
All resizing runs in your browser, so uploads are not required. Files stay private and results download instantly without server queues.
Upload once, set a KB target, and download a lighter file with predictable results.
Drop a JPG, PNG, or WebP into the uploader. The preview appears immediately so you can start tuning size.
Type the KB target, pick JPG or WebP, and adjust dimensions only if you need extra reduction.
When the estimate meets your limit, save the resized image. You can tweak again without reuploading.
Perfect for upload caps on forms and marketplaces. Dial in a KB goal, keep clarity where it matters, and export a lightweight file in seconds.
Reduce in KBCommon questions about resizing images to a custom KB target.
The tool aims to match your target as closely as possible using quality and size adjustments. Final size can vary a few KB depending on image complexity. For strict caps, lower the target slightly and re-export.
Not always. For many photos, lowering quality or switching to WebP is enough. If the file is still too large, a small downscale (about 10–20%) often makes the biggest difference without obvious quality loss.
WebP usually delivers the smallest files with good quality, especially for photos. JPG is more universally supported and still efficient. Try both formats and choose the one that preserves details you care about.
High-contrast text and simple logos hold up best. Very low KB targets can introduce blur or artifacts, so consider simplifying backgrounds or reducing dimensions slightly to keep edges readable.
The tool will not enlarge the file. You can download the original-quality output immediately, or still change dimensions or format if you want a different look.
Yes. The output is re-encoded to keep the file small, so most metadata is stripped. If you need to preserve EXIF or camera data, keep a copy of the original.
Yes. Use the unit selector next to the target field to switch between KB and MB. Your uploaded image stays in place, so you can test larger targets instantly.
No. All processing happens locally in your browser. Files never leave your device, which keeps the workflow fast and private.
Yes. You can resize and download images for free, with no signup required. Processing happens locally in your browser, so there are no usage caps or hidden fees.
No. All resizing and compression run in your browser. Files never leave your device and are not stored on our servers, keeping your images private.
