Which tool do you need?
Every tool works the same way. You drop one image or a whole batch, Oli processes each file on your device, and you download the results one by one or together in a ZIP. Nothing is uploaded, so the size of a batch depends only on your device.
- A form or an email turns down a big photo: Compress image makes the file lighter, and the presets above aim at 100 KB or 1 MB.
- A site asks for exact dimensions: Resize image sets the width and the height in pixels or by percentage.
- Only part of the picture matters: Crop image keeps that part, as a square, 4:5, 16:9 or a free shape.
- A photo came out sideways: Rotate image turns it 90° or 180°, or mirrors it.
- An iPhone photo does not open on your computer: HEIC to JPG turns the HEIC file into a JPG or a PNG.
- A WebP image has to be a JPG or a PNG: WebP to JPG converts it.
- A PNG has to be a JPG, or a JPG a PNG: PNG to JPG converts it either way.
- Several pictures have to go as one document: Image to PDF puts them in one PDF, one image per page.
Each tool also leaves the photo metadata out of the copy you download, so the GPS location of a phone photo stays with you.
