Image workflow guide
Choose JPG, PNG, or WebP
Pick a format based on the image's contents and the software that must open it. Converting formats can change transparency, detail, and file size.
Use JPG for photographs and broad compatibility
JPG uses lossy compression and does not support transparency. It is a common choice for photographs when a smaller file matters. Repeatedly saving a JPG at lower quality can add visible artifacts, especially around text, sharp edges, and fine patterns. Keep a lossless original if you may need to edit the image later.
Use PNG for transparency and crisp graphics
PNG preserves exact pixel values and supports transparency, making it useful for logos, interface screenshots, diagrams, and images with sharp edges. Photographic PNGs can be much larger than JPGs. If a conversion tool flattens transparency, the transparent area will be replaced by a background color; inspect the preview before saving.
Use WebP when the destination supports it
WebP supports lossy and lossless encoding and can include transparency. It is often a good choice for web delivery, but some older applications and workflows may not accept it. Check the requirements of the site, document, or editor where the file will be used.
Resize before judging file size
Pixel dimensions often matter more than format alone. An image used at 1200 pixels wide usually does not need to remain 5000 pixels wide. Use Resize Image to set dimensions, Compress Image to compare quality and size, or Convert Image Format to change formats. Save a copy and inspect fine details and transparent areas at the intended display size.
