# Compress Image to KB

Compress images to your target file size. Adjust quality to control the output size.

Plenty of upload forms don't just suggest a size — they reject anything over it. A government portal that caps a photo at 200KB, a job board that won't take a resume photo above 1MB, a forum avatar limited to 100KB: miss the number and the upload bounces. This tool is built around hitting that target. You compress toward a specific size in KB by dialing the quality down until the output lands under the limit, with the resulting file size shown so you know exactly where you are. It's an iterative nudge — push quality lower, watch the KB drop, and stop the moment you're safely under the cap. Because it recompresses the existing image rather than changing its dimensions, you keep the same width and height while the bytes come down. Everything runs locally in your browser, so the file never leaves your device.

## How it works

1. **Upload Images** — Select or drag and drop images you want to compress
2. **Adjust Quality** — Set your preferred quality level to balance size and appearance
3. **Download** — Get your compressed images with significantly reduced file sizes

## Use cases

- **Government and Visa Forms**: Get a passport-style photo under a fixed KB limit that won't accept anything larger.
- **Exam and Job Portals**: Fit a signature or photo into the exact size the application requires.
- **Forum Avatars**: Squeeze a profile picture under a small fixed cap like 50 or 100KB.
- **Legacy Systems**: Meet the tight upload ceilings older internal tools still enforce.

## Tips

- **Aim Just Under the Cap**: Land a little below the limit, not exactly on it — some systems count overhead and reject borderline files.
- **Watch the KB Readout**: Adjust quality in small steps and check the output size after each so you don't over-compress.
- **Resize for Tight Targets**: If a 100KB cap won't budge at acceptable quality, scaling the dimensions down frees up far more room than quality alone.
- **JPG Hits Targets Easier**: For photos, JPG compresses harder than PNG, so it's usually the friendlier format for a strict KB limit.

## FAQ

### Can I compress to an exact KB size?

You compress toward a target by lowering quality while watching the file-size readout, then stop once it's under your cap. Exact-to-the-byte sizes usually take a couple of small adjustments.

### How do I know when I've hit the target?

The output file size updates as you adjust quality, so you can see the KB figure drop below the limit before downloading.

### What if quality alone won't get me low enough?

Reduce the image's dimensions too — fewer pixels make a far smaller file, which is the only way to hit very low caps cleanly.

### Does this change the image dimensions?

No. Compressing to a KB target keeps the width and height the same; it only reduces the file's weight unless you choose to resize as well.

## Problems solved

- Uploads rejected for exceeding a KB limit
- Guessing whether a file is small enough
- Passport and form photos over the size cap
- Strict avatar and attachment ceilings
