What is this tool?
Image compression reduces file size by changing quality, format, or dimensions. It is useful before uploading photos to websites, forms, AI tools, blogs, email attachments, marketplaces, and social platforms.
How to use it
Choose an image, select JPEG or WebP output, adjust quality, then download the compressed result. To target a smaller upload limit, lower quality first and resize large photos if needed.
Common uses
- Reduce a photo before uploading it to a form, blog, or marketplace listing.
- Make images smaller for email attachments and chat apps.
- Create lighter web images that load faster on mobile connections.
Common mistakes
- Do not lower quality so far that text, faces, or product details become unclear.
- PNG screenshots and logos may look worse if converted to low-quality JPEG.
- Large pixel dimensions can keep a file big even when quality is reduced.
Practical example: Compress an image under 1MB
Start with WebP or JPEG at about 75% quality. If the result is still too large, resize the image to a smaller width such as 1200px and compress again.

Frequently asked questions
Are my images uploaded?
No. Images are processed locally in your browser.
How do I compress an image under 1MB?
Choose JPEG or WebP, reduce the quality slider, and download the result. If it is still too large, resize the image to fewer pixels first.
Which format compresses best?
WebP often creates smaller files, while JPEG is widely compatible. PNG is best for sharp graphics and transparency.
Can I use this before uploading images to AI tools?
Yes. Compressing large screenshots or photos can make uploads faster while keeping enough visual detail.
