Resize, compress and convert images

Why convert images in the browser?

Most online converters ask you to upload a photo to a remote server, wait for processing, then download the result. That workflow is fine for a public marketing asset, but it is a poor fit for screenshots that contain personal data, product shots that are not public yet, or ID scans you only need for a form. Image Reshaper keeps the entire pipeline on your device: the file is decoded with the browser’s image APIs, drawn to a canvas, re-encoded, and saved as a local download.

Because nothing is sent to our servers for conversion, closing the tab is enough to discard the working copy. Optional analytics may record which tools people open; those events never include filenames, pixel data, or EXIF. In the EEA, UK, and Switzerland, analytics and advertising storage stay denied under Consent Mode until a consent choice updates them. The product exists so a search result can finish a small job without creating an account.

Choosing JPG, PNG, or WebP

JPG (JPEG) is the everyday format for photographs. It compresses well, but it cannot store transparency and it discards fine detail each time you re-save at a lower quality. PNG is lossless and can keep an alpha channel, which makes it the right choice for logos, UI screenshots, and graphics with sharp edges. The trade-off is file size: a PNG photo is often much larger than the same scene as JPG.

WebP sits between them for many web use cases. It can be lossy or lossless, can keep transparency, and often beats JPG or PNG on byte size at a similar visual quality. Support in current Chrome, Edge, Firefox, and Safari is solid. Older desktop software, some email clients, and a few print workflows still expect JPG or PNG, which is why this site offers conversions in both directions.

• Use JPG for photos destined for print forms, older apps, or maximum compatibility.
• Use PNG when you need lossless pixels or a transparent background.
• Use WebP when the destination is a modern website or app that already accepts it.

What you can do here

Beyond one-click format conversion, Image Reshaper includes an image compressor that aims for a target file size, dedicated landings for 100 KB and 200 KB caps, a resizer for exact pixel dimensions, a cropper with common social presets, rotate and flip tools, metadata stripping, Base64 export, and a favicon generator. Every available tool follows the same privacy rule: processing stays in the browser within the documented size and dimension limits.

If you are new to the site, start with the converter on this page, then browse Available tools for the job you need. The guides section walks through common tasks such as shrinking a photo for an email attachment or converting JPG to PNG when you plan to edit transparency later.
