Practical checks before and after an image task, with outputs measured using MiruKit rather than assumed savings.
You've reached the photo attachment on an application, but your iPhone picture is grayed out. Check whether the form accepts HEIC. If it asks for JPG, make a copy of the photo you need and keep the original in your library.
You have a photo file from a photographer, but the application asks for a size you don't recognize. Start with the country and submission method. Separating the printed size from the upload dimensions makes it much easier to prepare the right copy.
You've finished an application and the last photo attachment hits a 200KB limit. Match any required dimensions first, then choose submission JPG and 200KB in Compress. That gives you a clear sequence instead of repeatedly saving and guessing.
You want a small image for a website, but your application form accepts only JPG. Start with where the file will go. Use JPG for that form, try WebP for web publishing, and consider PNG for a transparent logo or a pixel-exact copy.
Your email has a handful of photos attached and the total is too large. Before dragging quality all the way down, check the size your recipient needs. Leave photos that already fit alone and make smaller copies of the large ones from the originals.
A product handle has disappeared, or a character's shirt has a hole after background removal. Try the brush in Add mode on the missing part first. Use Subtract on leftover background, then apply transparency to check the result.
You're posting a photo of something for sale and wonder whether its home location will travel with it. Remove capture information from the sharing copy, then check the filename and anything visible in the picture. Keep your private original separately.
A shipping label is visible in a listing photo, or a stranger's face appears in a travel picture. Select a little beyond the area you want to hide and apply mosaic. For sensitive numbers, consider an opaque cover or cropping the information out entirely.
You took a photo beside a window, but the person looks much darker than the view outside. Raising the brightness fixes the face and turns the window white. Try Shadows first when one part of the picture is dark; use Exposure when the whole picture needs more light.
An old photo looks fine as a thumbnail, then turns soft when you use it in a larger layout. Before choosing AI, decide how large it actually needs to be. Making an image occupy more pixels and inventing plausible detail are different jobs, and they need different checks.
An upload form asks for โ300 DPI,โ but your photo says 72. Will changing that number make a small image clearer? Separate the pixel dimensions from the size on paper first. We changed only the density information in one 960ร600 JPG and checked what actually happened.
Someone asks you to send three receipts as one file. A long stitched image makes them scroll and zoom, and sending separate attachments makes it easy to miss a page. A PDF with one photo per page is easier to review in order and print when needed.
