Can I set a target size in KB?
Yes. This page includes size reduction settings designed for practical target-based compression.

What This Processing Changes
Compression and optional resizing re-encode the image. A smaller target can reduce fine detail, and a requested byte size is best effort rather than exact for every source.
How to Check the Result
- Read the downloaded byte size; a requested target is not an exact-size guarantee.
- Zoom in on small text and edges before accepting stronger compression.
Limits and Troubleshooting
- Reduce pixel dimensions before forcing very low quality.
- Use PNG only when transparency or lossless graphics matter; photographs are often smaller as JPG or a modern web format.
What This Image Compressor Is For
This compress image tool is for reducing file size while keeping the image usable for uploads, websites, forms, and sharing. It works well when a file is too large to send by email, too heavy for a web page, or rejected by an upload limit.
Start with the destination’s byte limit, then check the downloaded file size. If small text becomes blurry, lower dimensions only as far as the destination allows instead of repeatedly lowering quality.
How To Balance File Size And Quality
Compression works best when you choose the final purpose first. For forms and messaging, smaller files are usually fine. For product photos, articles, or client delivery, it is often better to keep a slightly larger file to protect clarity.
If a file is still too heavy after compression, resizing the image dimensions can improve results more than pushing quality too low.
Frequently Asked Questions
Will compressed images lose quality?
Some formats may lose a small amount of detail, but the goal is to keep the result visually useful for the chosen purpose.
Should I resize before compressing?
If the image dimensions are much larger than needed, resizing first usually gives a better balance of size and clarity.
