Compress PNG, JPG, JPEG, and WebP images with quality and max-width controls, without uploading the image.

WebP quality
78%
Lower quality usually creates a smaller file. Higher quality keeps more detail.
Maximum output dimension is 8000px per side to keep browser memory usage reasonable.
Compress images before uploading them to websites, blogs, CMS libraries, email campaigns, or product pages where file size affects load time and Core Web Vitals.
Use the optional max-width setting when you want to reduce both pixel dimensions and file size for hero images, article thumbnails, or screenshots that do not need full source resolution.
WebP is usually the better default for modern sites because it often produces smaller files than JPG and can preserve transparency from PNG sources.
JPG is useful for broad compatibility, email workflows, and legacy systems, but transparent pixels are flattened onto the selected background color.
The most common mistake is lowering quality too far before checking text, UI edges, or product details. Quality values around 70 to 82 usually work well for photos, but screenshots and diagrams usually need more.
If the compressed file is still too large, reduce width as well as quality. A blog hero often does not need more than 1600px, and many inline article images work fine at 1200px or 1024px.
The browser decodes the source image, draws it onto a canvas, and re-encodes it as a compressed file. In practice, a multi-megabyte upload can often become a few hundred kilobytes when width and quality are tuned for web delivery instead of archival storage.
No. The compression runs locally in your browser with Canvas APIs. Your image is not uploaded or stored by this tool.
PNG is lossless and often not ideal for heavy compression. This tool re-encodes images as JPG or WebP so you can reduce file size.
Yes. Lower quality values usually create smaller files, but they can add blur, banding, or artifacts. Preview the result and adjust quality as needed.
Large source images often shrink by 40% to 80%, especially when you combine lossy output with a smaller max width. The exact result depends on the source format and image detail.
