Image Guide
The image category has four groups: Edit & Convert for basic photo touch-ups, Generate & Extract for pulling something out of an image or layering something new onto it, Platform Assets for fitting fixed size specs, and PDF for document work.
If you're stuck on "what file type am I dealing with" rather than "what do I want to do," photo files live in the first three groups and document files live in PDF.
All nineteen tools process images and PDFs using only the canvas and browser APIs, with nothing uploaded anywhere, so even a large source file processes quickly regardless of your connection speed.
Image formats are chosen by purpose. Photographs with smooth colour gradients suit JPEG for quality per byte, while logos and shapes with hard edges and few colours stay cleaner as PNG. Transparency requires PNG or WebP, which JPEG cannot carry.
JPEG discards information on every save. Repeatedly opening and re-saving degrades the image visibly, so work in a lossless format and convert once at the end.
There are two ways to reduce file size: lowering resolution and raising compression. For screen-only images, matching the resolution to the actual display size cuts size sharply, while print work needs the resolution preserved.
Photo files store capture information alongside the image — camera model, time, and sometimes location coordinates — so posting a photo unaltered can reveal a home or workplace. Checking and stripping it before sharing is the safer habit.
PDF is a document format and behaves differently from an image. Merging pages, extracting a few, and reducing size are common needs, and a scanned PDF holds its content as images, so text search will not work.
Thumbnails and banners have recommended dimensions per platform. A mismatched ratio is cropped automatically and pushes important content out of frame, so leaving margin around the centre keeps the subject intact whatever the crop.
App icons and favicons need several sizes prepared together. Detail disappears at small sizes, so a simple shape that stays distinguishable when reduced works better, and lettering is usually illegible.
Areas hidden by mosaic or blur are sometimes recoverable. Weak blurring allows the original to be inferred, so covering the region in solid colour is the reliable way to hide personal information.
Watermarks need both position and opacity decided. Placed only in a corner they are easy to crop away; placed heavily in the centre they make the image unusable — the strength follows the purpose.
Extracting a palette from an image makes matching design colours easier, though extracted colours often lack contrast when applied to text, so brightness difference against the background needs separate checking.
These tools process images inside the browser. Files are not uploaded, so personal photographs and documents stay local.
Adding text to an image starts with deciding the final display size. Captions made on a large screen often become illegible in a list thumbnail, so checking at the reduced size settles the type size reliably.
Stitching several images together requires matching resolutions. Joining images of different sizes stretches one or leaves a gap, so decide in advance whether to crop to the shorter side or fill with a background colour.
