Image Compressor
Shrink JPG, PNG and WebP images by lowering quality and maximum width, see exactly how much space you saved, and download the result.
About the Image Compressor
The Image Compressor makes photos much smaller so they upload faster and fit email and form limits. Set the quality and maximum width yourself, or just pick a target like 50 KB, 100 KB or 200 KB and let it find the right settings. A bar chart shows the size before and after, and a drag slider lets you compare the two pictures.
What you can do with the Image Compressor
- Target size: Pick 50 KB, 100 KB or 200 KB and it finds the settings.
- Manual control: Set the quality and maximum width yourself.
- Before vs after: A bar chart and a drag slider to compare.
- Stays on your device: The photo is never uploaded.
Hitting a KB limit
Many government, exam and job application forms only accept photos under a certain size, such as 50 KB or 100 KB. Choose that target and the compressor searches for the best quality that fits, reducing the width only if it has to, no more trial and error.
Width matters most
A typical 12-megapixel phone photo is about 4000 × 3000 pixels. Limiting it to 1280 px wide cuts the number of pixels by around 90%, which shrinks the file far more than lowering quality alone, and it still looks sharp on phones and laptops.
Finding the right quality
Quality between 60% and 80% is usually the sweet spot. Below about 50%, blocky artefacts start to appear, especially in skies and smooth gradients, drag the comparison slider to check. WebP files are typically a quarter to a third smaller than JPG at similar quality. Re-saving also removes hidden metadata such as GPS location.

Frequently Asked Questions
How do I compress an image to under 100 KB?
Tap "100 KB" under Target file size. The tool finds the highest quality that fits and shows the final size.
Why did my file get bigger?
Images that were already heavily compressed can grow when re-saved at high quality. Lower the quality or width, choose a target size, or keep the original.
Is compression reversible?
No. Compression permanently discards detail, so keep your original file if you might need full quality later.
How do I compress a photo to 20 KB?
There is no 20 KB button, so turn Target file size off and set it manually: choose a smaller maximum width like 800 px and lower the quality until the size shown is under 20 KB. Check your form's instructions for both the KB limit and the pixel size.
Should I choose JPG or WebP?
WebP files are usually noticeably smaller at the same quality, which is useful for websites. Many application and exam forms accept only JPG or JPEG, so choose JPG for those unless the form clearly lists WebP.
What quality setting should I use?
The default 70% gives a good balance for most photos. Between 60% and 80% the difference is usually hard to see on a phone screen, while very low settings show blocky patches around edges and text. Use the drag-to-compare slider to check before downloading.
Does compressing change the photo's dimensions?
Only if it is wider than the maximum width, which is 1280 px by default. Choose Original to keep the full width, or pick 2560, 1920, 1024 or 800 px. If a form needs exact pixel dimensions, use the Image Resizer for that first.
What happens to a transparent PNG?
The output is JPG or WebP. JPG does not support transparency, so transparent areas become white. WebP keeps transparency, so choose WebP if you need a see-through background.
Why does it say it couldn't get the image under the target?
It first searches for the highest quality that fits, then shrinks the width in steps if quality alone is not enough. Very detailed or very large images may still not fit. Choose a smaller maximum width, or a larger target such as 100 KB.
Is 50 KB measured as 50,000 or 51,200 bytes?
The target uses 1 KB = 1,024 bytes, so 50 KB means up to 51,200 bytes. Some websites count 1 KB as 1,000 bytes, so a file near the limit could be rejected. If that happens, use manual settings to get a little under, like 45 KB.
Does compressing remove location and camera details?
Yes. The photo is redrawn and saved as a new file, so metadata such as camera model, date and GPS location is not carried over, which is useful before sharing photos publicly. The compression happens in your browser and the photo is not uploaded.
