About this tool
Image Compressor reduces the file size of JPG, PNG, and WebP images without changing their dimensions. Drop in an image, drag the quality slider (or pick a preset), and download a smaller copy. A live side-by-side preview shows the original next to the compressed result, with exact size and savings.
Example: a 3.2 MB phone photo re-encoded to WebP at 75% quality typically lands around 280 KB — roughly a 90% reduction with no visible quality loss. The format comparison table shows the same image encoded as JPEG, WebP, and PNG at the chosen quality so you can pick the smallest option.
Useful for trimming page weight before uploading to a CMS, shrinking email attachments, fitting images under a hosting size limit, and converting PNG screenshots to WebP.
FAQ
What is the difference between this and the Image Resizer? ›
Image Resizer changes the pixel dimensions (width × height). Image Compressor keeps the dimensions identical and reduces file size by re-encoding at a lower quality or a more efficient format like WebP.
Which format should I choose? ›
WebP gives the smallest files for most photos at equivalent visual quality. JPEG is the safest for broad compatibility. PNG is lossless and best for graphics with sharp edges or transparency, but it will not shrink much.
Why does my PNG get larger after compression? ›
PNG is already lossless, so re-encoding it cannot remove information. If the PNG source was already well optimized, the re-encoded file may be slightly bigger. Switch the output format to WebP or JPEG to get a real reduction.
What happens to transparency when I convert to JPEG? ›
JPEG does not support transparency. Transparent areas are filled with white, which is the standard behavior. Keep PNG or WebP if you need to preserve transparency.
