Picking a format without guessing
The format decision comes down to what the image contains — this is what the Image Converter handles. Photographs — continuous tone, no hard edges, no transparency — belong in a lossy format, and JPEG remains the safe universal choice while WebP typically produces a noticeably smaller file at equivalent quality. Graphics with flat colour, sharp edges, or text — logos, screenshots, diagrams, anything with a transparent background — belong in PNG, because lossy compression makes a visible mess of hard edges and PNG supports genuine transparency.
The most common expensive mistake is saving a screenshot as JPEG. Screenshots are full of exactly what JPEG handles worst: crisp text and flat colour blocks. The result is visible fringing around every letter, and often a larger file than the PNG would have been. The reverse mistake — a photograph saved as PNG — produces a technically perfect image at several times the necessary size.
AVIF compresses better than both for photographs and is now widely supported, though it is worth checking your specific audience before committing to it as the only format. And a point that surprises people: re-encoding a JPEG loses quality every time, even at maximum quality, because the lossy step runs again on already-degraded data. Always work from the original where you can, rather than a copy that has already been through the process.
Order of operations, and the metadata point
When you need a smaller file, resize before you compress. Reducing a 4000-pixel-wide photo to the 1200 pixels a web page actually displays removes most of the data outright, and compression then works on a much smaller image. Doing it the other way — compressing hard at full resolution then shrinking — degrades quality to fix a problem that resizing would have solved cleanly. For general web use, 1200 to 1600 pixels on the longest edge is usually plenty.
Separately from size: photographs taken on a phone carry EXIF metadata, and that routinely includes precise GPS coordinates of where the picture was taken, along with the device model and exact timestamp. This travels with the file when you upload it, email it, or post it somewhere that does not strip it — and many platforms do not. If you are sharing photos taken at home, that is your home address embedded in the file. Stripping metadata before sharing takes seconds and the image itself is unchanged.
Image Cropper, Background Remover, and Image Watermark handle a different job from format and size — content, not encoding. Cropping and watermarking are the two people reach for right before publishing something, respectively removing what should not be in frame and adding what should always be traceable back to its source. Background removal is the odd one out technically: it runs a real segmentation model (ONNX Runtime, entirely client-side) rather than a simple pixel operation, which is why it is slower than the others and why results vary more with subject contrast and edge complexity than a resize or crop ever would.
