Compress Image to 20KB
Compress an image to 20KB online with a target-size workflow tuned for application forms and signature uploads. Upload one image, set the budget automatically, and download a lighter file without installing desktop software.
This page is built for people who already know the file-size limit they need to hit. Instead of guessing quality settings, it keeps pushing the file down until it lands at or below the target budget.
How to use this page
- Upload one JPG, PNG, SVG, HEIC, HEIF, or AVIF image to start the 20KB workflow.
- Review the target-size preset, then let the tool iteratively reduce file weight until it lands at or under 20KB.
- Preview the output, confirm the final size, and download the processed file.
When to use this workflow
- Use this route when a website or form gives you a hard 20KB limit.
- Choose Compress to Size when you want to preserve dimensions as much as possible.
- Switch to Resize to Size instead when the file is too large to hit the goal through compression alone.
Supported formats and expectations
- Best inputs: JPG, PNG, HEIC, HEIF, AVIF, and browser-supported image uploads
- Typical outputs: auto-selected image format, JPG, WEBP, or PNG depending on the preset
- Best for: form uploads, profile photos, and attachment limits
Limits to keep in mind
- The result aims to finish at or under 20KB, not hit the exact byte count every time.
- Aggressive size targets can introduce visible artifacts on detailed photos.
- Some images may need format changes or heavier quality reduction to fit small budgets.
Launch the underlying target-size tool with the preset already selected.

Frequently asked questions
Will the image dimensions stay the same?
The tool tries to preserve dimensions first, but aggressive targets may require more visible compression or a more efficient output format.
Should I use compression or resizing first?
Start with compression when you want to keep the original dimensions. Use resizing when the budget is too strict for quality-only reduction.
Does this run in the browser?
Yes. This workflow is designed for browser-side processing in the current phase.
