Image Size Reducer
Type the exact file size a form or portal asks for and this tool searches for the highest quality that still fits under it. Useful for job applications, exam boards and visa forms that reject anything over a stated limit.

- Drop in your photo.
- Type the target size in KB or MB.
- Download the result once it lands under your limit.
Features
- Target size in kilobytes or megabytes, not just a quality guess.
- Tries progressively lower quality and, if needed, smaller dimensions to reach the target.
- Reports the exact result size next to your target.
- Works on JPG, PNG, WebP, GIF and BMP files.
What happens if the target cannot be reached?
Most photos reach a small target like 50 or 100 KB comfortably. If a file genuinely cannot get small enough at a readable quality, usually because the target is extremely small for a large photo, the tool tells you plainly instead of returning a broken or unreadable image.
How does the tool find the right quality automatically?
It searches rather than guesses: starting from a wide quality range, it encodes the image, checks the resulting size against your target, and narrows the range up or down until it settles on the highest quality that still fits. If quality alone cannot reach a very small target, it steps the pixel dimensions down as well and searches again at the smaller size, rather than forcing the quality so low the image becomes blotchy.
Why do job portals and exam boards set such small size limits?
Older government and university upload systems were often built years ago on limited server storage, so a 50 or 100 KB cap that seems tiny by today's camera standards is really just a legacy limit nobody has raised. It catches out anyone uploading a modern phone photo, which typically runs 2 to 8 MB straight out of the camera, dozens of times over the limit before any compression at all.
Frequently asked questions
How close does the result get to my target size?
Within 5 percent under your target in almost all cases. The tool would rather land slightly under than risk going over a strict limit.
Will it change the dimensions of my photo?
Only if quality reduction alone cannot reach the target. In that case it scales the image down in small steps until the target size is met.
Can I use this for a passport or visa photo size?
This tool controls file size only, not the exact pixel dimensions a passport photo needs. Use the Passport Photo Resizer for the correct dimensions and DPI.
What is the smallest target size I can enter?
There is no hard floor in the tool itself, but extremely small targets like 5 or 10 KB for a large, detailed photo may not be reachable at a readable quality, and the tool will say so rather than produce a broken file.
Does the target size include or exclude the file's own header?
It includes everything: the target you type is the final file size on disk, header and all, matching what an upload form actually checks.
Should I convert to JPG first for a smaller result?
Usually yes for a photo. JPG's lossy compression reaches a small target at a much higher visible quality than PNG for the same file size, since PNG has to reduce colours instead of detail. Use the Image Converter first if your source file is a PNG photo.
