Shrink any photo to under 20 KB for online forms, keeping it as sharp as possible. How it works: Choose one or more images. Check the target size (20 KB) and, if the form specifies dimensions, enter the maximum width. Press "Compress".
About the Compress Image to 20 KB
This tool compresses a photo until it is under 20 KB, the size limit typically used for signatures and thumb impressions on exam and recruitment forms, which are often limited to 10–20 KB. Instead of guessing a quality setting, it searches automatically for the highest quality that still fits the limit and only reduces the dimensions if that is not enough.
You can change the target, keep or cap the pixel dimensions and choose JPG or WebP output. PNG, WebP, GIF, BMP and iPhone HEIC photos are accepted. Everything happens in your browser: the file never leaves your phone or computer, is not uploaded to any server and is not stored by News Appite.
Every file shows its before and after size, and batches are supported, so you can prepare a photo, a signature and a document scan for the same form in one go.
How to use the Compress Image to 20 KB
- Choose one or more images.
- Check the target size (20 KB) and, if the form specifies dimensions, enter the maximum width.
- Press "Compress".
- Download the result; the final size and dimensions are shown for each file.
Tips & benchmarks
- Forms that also specify dimensions (for example 200 × 230 pixels for photos) should be matched with the maximum width field.
- Crop away empty background first: fewer pixels means more quality within 20 KB.
- Always confirm the exact limits in the official notification before applying.
- Signature scans compress best in black ink on white paper, cropped tightly around the signature.
Frequently asked questions
How do I reduce a photo to 20 KB?
Add the photo and press Compress. The tool tries quality levels automatically and gives you the best-looking JPG that is under 20 KB.
Why is my image still blurry at 20 KB?
Very large photos have to lose resolution to fit a small limit. Cropping to the important area or setting a smaller width first gives a sharper result.
Which formats are supported?
JPG, PNG, WebP, GIF, BMP and HEIC in; JPG (or WebP) out.
Is my photo uploaded?
No. It is compressed in your browser.
Can I compress a PNG to 20 KB?
Yes. PNG images are converted to JPG, which is far more efficient for photos, and compressed under 20 KB. Transparent areas become white.
Will the photo still be accepted by the portal?
The output is a standard JPG that portals accept; also check the required pixel dimensions and background, which the size limit does not cover.
Can I choose a different size?
Yes. Type any target size in KB, for example 30 or 80 KB.
How can I compress an image to 20KB without losing quality?
This tool automatically searches for the highest quality that still fits the 20KB limit, reducing the dimensions only if necessary, to ensure your photo remains as sharp as possible. You can also choose to keep or cap the pixel dimensions and select either JPG or WebP output. The tool supports various input formats, including PNG, WebP, GIF, BMP, and iPhone HEIC photos.
Can I compress an image to 20KB with specific height and width?
Yes, you can specify the maximum width for your compressed image, which is useful if the form you're filling out has specific dimension requirements. The tool will then adjust the quality and dimensions accordingly to fit within the 20KB limit. Simply enter the target width when using the tool.
How can I reduce the size of an image to 20KB without losing quality?
This tool is designed to shrink photos to under 20KB while maintaining their sharpness. It achieves this by automatically finding the optimal quality setting that fits within the size limit, and only reduces the dimensions if necessary. This ensures your image remains clear and usable even at a smaller size.
