Downloads are JPG. Transparent areas become white. Large images may be resized to meet the size limit; animated images are not supported.
Choosing 100 KB for your image
This preset caps the JPG at 100,000 bytes. It offers more room than 50 KB for a portrait or a simple illustration while keeping the file small. Use it when your form allows 100 KB; check its dimensions and accepted formats as well.
Keeping text and faces readable
A full page of dense text can become hard to read at this size. Inspect the downloaded result at its actual size, especially small letters and fine lines. This tool cannot crop the image or increase clarity in a blurry original.
If the destination allows a 200 KB file, that preset may keep more detail. If it requires 50 KB, switch to the smaller preset and inspect the result again.
How to reduce your image size
- Choose the maximum file size required by your upload form.
- Select a JPG, PNG or static WebP image from your device.
- Press Compress, inspect the preview, then download your JPG.
Check the form's pixel dimensions and file-format rules separately. Meeting a file-size limit alone does not guarantee your image will be accepted.
What happens to your image?
FileMelon adjusts JPG quality and, when needed, reduces pixel dimensions. Your original file stays unchanged. Processing happens on your device; the image is not sent to our server.
Frequently asked questions
Will the result be exactly the selected size?
No. The target is a maximum: 50 KB means at most 50,000 bytes. A smaller result is normal. FileMelon uses decimal KB, which is slightly stricter than the same number of KiB.
Can I keep PNG transparency?
This tool downloads JPG files. Transparent areas become white. Keep your original PNG if you need a transparent background.
Why can a small PNG become a larger JPG?
Converting formats can increase file size, especially for simple graphics. The result still stays within your selected limit. If your original already meets the form's requirements, you may prefer to use it.
Which files can I use?
JPG, PNG and static WebP files up to 20 MiB and 40 megapixels. Animated images are not supported. A modern browser with JavaScript enabled is required. Very large images can be demanding on older devices.
Starting with an HEIC or AVIF photo?
Convert HEIC / HEIF to JPG or convert AVIF to JPG first, then return here with the downloaded JPG. For official applications, check that conversion is allowed; keep your original photo.
