Compress Image Online for Free
Use this free Image Compressor to reduce image file size directly in your browser. Compress supported JPG, PNG and WebP images for websites, email, online forms and everyday sharing. You can adjust image quality, select an output format and optionally resize the image width.
Compress Image to 20KB, 50KB, 100KB or More
If a website or application specifies a maximum image size, enter your desired target in KB. The compressor will try different quality settings to get close to your target. Results depend on the image's dimensions, format and content, so the requested size cannot always be reached without reducing dimensions or changing format.
- 20KB: For very small image-size limits, if image detail allows.
- 50KB: A common target for smaller image uploads.
- 100KB: Useful when a form allows a larger image file.
- 200KB and above: May allow better image quality.
These are example targets, not universal requirements. Always check the instructions for your specific form or website.
How to Compress an Image
- Select a JPG, PNG or WebP image from your device.
- Optionally enter a target file size in KB.
- Select JPG, WebP or PNG as the output format.
- Adjust quality or enter a smaller output width if needed.
- Click Compress Image and compare the previews and file sizes.
- Click Download Image to save the result.
Which Image Format Is Best?
JPG
JPG is useful for photographs and often produces smaller files. It uses lossy compression and does not support transparency.
WebP
WebP can produce compact images for supported websites and applications. Check that your destination accepts this format before using it.
PNG
PNG is useful for graphics, screenshots and images requiring lossless compression or transparency. A PNG image may remain large; converting a photo to PNG does not necessarily reduce its size.
Does Image Compression Reduce Quality?
Lossy compression can reduce detail, especially at low quality settings. Resizing an image also reduces its pixel dimensions. Always inspect the compressed result before uploading it, especially when text, small details or document readability matters.
Is This Image Compressor Private?
This tool processes the selected image locally in your browser rather than sending it to a conversion server. For sensitive documents, use a trusted device and review the downloaded file before submitting it.
Frequently Asked Questions
Can I compress an image to exactly 50KB?
The tool attempts to reach the target size, but exact file sizes cannot be guaranteed for every image. Try a smaller width or a different output format if necessary.
Can I compress an image to 100KB or 200KB?
Yes. Enter 100 or 200 in the target-size field. The result depends on image content, dimensions and format.
Can I use this tool on mobile?
Yes. The interface adapts to mobile screens, although processing very large images may take longer on some devices.
Will compression change the image dimensions?
The dimensions stay the same unless you enter a new output width. The height is calculated proportionally to preserve the aspect ratio.
Why is my PNG still large?
PNG is a lossless format and can be large for photographs. JPG or WebP may produce a smaller file if your destination supports that format.
