Image tools: convert, resize and organize files
Images arrive as photos, screenshots, scans and graphics. The right next step depends on what you need to send or publish. These guides and browser tools help you prepare a copy, check the result and preserve the original.
Start with the task
If someone needs a single document, arrange images into a PDF and check the page order. If the goal is a smaller attachment or faster page load, try resizing or compression on a copy. If an app rejects the file, convert its format only after checking which formats the recipient accepts.
Make a document from photos
The image-to-PDF guide explains how to arrange photos into pages and review the result. A PDF groups content into one document but does not automatically make it smaller; text, page order and file size still need checking.
Resize, compress or crop a copy
Resizing changes pixel dimensions; compression changes how image data is stored; cropping removes part of the frame. These operations solve different problems. Keep the original, compare the exported copy at its intended display size and avoid a fixed pixel target for every use.
Choose a format for the content
JPEG commonly suits photographs but uses lossy compression. PNG is a lossless raster format with transparency. WebP can use lossy or lossless compression and supports transparency and animation. SVG describes vector graphics that scale to different display sizes; it is usually suited to icons and illustrations rather than ordinary photos. The best choice depends on the image and the software or service that must open it.
Good habits before sharing
Keep an untouched original. Check that small text and fine edges remain clear, confirm the export format is accepted, and open the resulting file once before sending. For images of documents, confirm that the recipient accepts an image or PDF and share only what is required.

Frequently asked questions
Which format should I choose for a photograph?
Compare JPEG with WebP or AVIF when the destination supports them. Keep the original and inspect the exported copy; no format produces the same size or quality for every image.
Will converting photos to PDF always make them smaller?
No. A PDF groups pages into a document, but its size depends on the images and export settings. Check readability and file size before sharing.
Should I overwrite the original image?
Keep the original and edit or convert a copy so you can return to the source if you need another size or format.
