Image Compressor
Compress JPG, PNG and WebP images locally in your browser.
Compress images locally
Select an image and adjust quality. The browser creates a compressed version without sending the original file to our server.
Quality and file size
Lower settings usually reduce file size more but may reduce visual quality.
Compression trades file size for image data
Lossy formats such as JPEG and WebP can reduce file size by discarding visual information. Lower quality settings usually create smaller files but can introduce blur, blocking or ringing. PNG compression is different because PNG is normally lossless, although converting or re-encoding can still change metadata or color handling.
Resize before extreme compression
If an image is much larger in pixel dimensions than the final display size, resizing it first can reduce the file size more effectively than forcing a very low quality setting. Keep a separate original copy when image quality matters.
Frequently Asked Questions
Are my images uploaded?
No. This version processes them locally in your browser.
Will compressing an image reduce its dimensions?
Compression and resizing are different operations. Compression can reduce file size while keeping the same pixel dimensions unless the tool also resizes the image.
Which format is best for photographs?
JPEG and WebP are commonly efficient for photographs. The best choice depends on browser support, transparency needs and the quality level you require.
