# Compress images for the web without making them look bad

> Compress photos to WebP in your browser with a quality range that still looks sharp. No upload.

You already picked dimensions, or the CMS did. Now the file is still 3 MB. Re-encode as WebP around quality 0.8. That is the boring, effective setting most marketing sites need.

## How to start

1. Drop the images already close to display size.
2. Keep WebP and quality 0.8. Nudge up if you see banding in gradients.
3. Optional: set a max width if a few files are still huge.
4. Replace assets on the site. Compare on a real phone as well as a 5K monitor.

## Notes

- Hero images tolerate 0.75 more than product close-ups.
- Don’t compress a file you already ran through three other “optimizers.” Start from the original.
- Check Lighthouse after deploy; this tool does not talk to your host.

## Price

Always free. There is no account, no paid tier, and no watermark.

## What this site does not do

- There is no upload API, no account, and no paid tier. Photos are not sent to or stored by the site.
- Output formats are JPG, PNG, WebP, and still GIF. SVG can be opened as an input and saved as PNG with transparency.
- HEIC and HEIF can be opened in current Chrome, Firefox, Safari, and Edge. A local decoder runs in the tab when the browser cannot decode HEIC itself. AVIF stills can be opened in current browsers.
- There is no convert-to-HEIC. Animated AVIF is not supported. GIF output is a still picture. An animated GIF becomes one frame.
- This site does not make PDFs. For converting images into a PDF, use JPG to PDF on [❤️ LoveThisPDF](https://lovethispdf.com/tools/jpg-to-pdf), which also runs in the browser.
- It does not add Content Credentials (C2PA). It can strip them on Remove EXIF & GPS.
- Converting JPG to PNG does not invent a transparent background.

## Requirements

Any phone, tablet, or computer with a browser. Nothing to install. HEIC and AVIF convert in current Chrome, Firefox, Safari, and Edge. A decoder runs in this tab when the browser cannot open HEIC itself. Very old browsers may still need a JPG from the iPhone. Very large images may fail if the device runs out of memory. Results can differ between browsers because encoders (especially WebP and JPEG quality) are implemented by the browser vendor.
