Convert the target to bytes
The KB value is converted to bytes (KB × 1,024), and every candidate result is compared with that limit.

What this tool does
This tool compresses JPG files toward a target KB or MB size directly in your browser. Choose the limit from your form, run compression, then review the result before your final upload.
Practical tips
- JPG is usually best for photos, portraits, passport images, and visa images.
- If a portal still rejects the file, check the maximum pixel dimensions too.
- For signatures or crisp graphics, PNG may be a better fit than JPG.

How ExactSizer targets a file-size limit
The target is treated as a maximum limit, not a promise that every source file can finish at exactly the same byte count.
02
Search for the highest usable image quality
For JPG, PNG, and WebP, the engine tests quality between 0.1 and 1.0 using 12 binary-search steps. If that is not enough, dimensions decrease in 5% increments down to a minimum of 10% of the starting dimensions. To bridge encoder size plateaus, it also tests higher-quality candidates and refines dimensions in 6 passes, always retaining the closest result under the limit.
03
Process locally and report the result honestly
The file is processed in browser memory. The result reports whether the target was met and shows a warning if minimum settings are reached before the requested size.

Frequently asked questions
These answers cover the questions people usually have before compressing a file.
Can I compress JPG to 100KB or 200KB?
Yes. Targets like 100KB and 200KB are common for forms, profile photos, and upload portals, and you can aim for them directly here.
Will JPG quality stay the same?
Exact-size compression always involves tradeoffs, but the goal is to keep the image as clear as possible while aiming for your target.
What if my JPG is still too large?
If quality changes alone are not enough, the tool can reduce the image more aggressively to get closer to the size you requested.
