Reduce image file size for sharing and faster pages
Photo compression can reduce the data needed to store an image by simplifying fine detail. A moderate quality setting often works well for everyday pictures, while text, repeated patterns, and strong edges can reveal artifacts sooner. Use the preview and resulting file size together to decide whether the tradeoff is worthwhile.
Choose JPG or WebP for adjustable photo compression
JPG and WebP support a quality setting that can change the size and appearance of the export. PNG uses lossless encoding, so a photographic quality slider does not shrink it in the same way. Converting a logo to JPG also removes transparency; keep PNG or WebP when transparent pixels are important.
Combine photo compression with sensible image dimensions
A large photo may still be too heavy even at a lower quality setting. If you only need a small web image, resizing it first can help more than aggressive compression. A new export is not guaranteed to be smaller than an already optimized source, so review the reported size before replacing your existing file.
Compress Image online: frequently asked questions
How can I reduce a photo's file size?
Choose JPG or WebP, lower the quality gradually, and compare the resulting size and appearance. Reducing pixel dimensions can help further.
Is the compressed image always smaller?
No. An already optimized source, a different format, or a high quality setting can produce a larger export. Check the result before saving over another copy.
Does a quality slider compress PNG?
PNG is lossless and does not use the JPG-style quality setting. For a smaller photographic file, try JPG or WebP, or reduce its dimensions.
Can I compress a transparent image?
Use WebP if you need transparency with adjustable quality, or PNG for a lossless transparent export. JPG replaces transparent areas with a solid background.
