Image Converter & Compressor

The Image Converter & Compressor changes an image from one format to another — JPG, PNG, WebP, or AVIF — right inside your browser.

It also compresses the result with a quality slider and can optionally shrink the dimensions, so a heavy photo becomes a lean, web-ready file. Every step runs on your device, so your pictures never leave your computer.

How to convert an image

1. Add your images. Click the upload box or drag files in — you can select several at once.
2. Pick the output format. Choose WebP, JPG, PNG, or AVIF depending on where the image will be used.
3. Set the quality. Nudge the slider down for smaller files, or leave it around 80% for a clean, web-friendly balance.
4. Resize if you want. Tick "Also resize" and enter a maximum width to cut the pixel dimensions at the same time.
5. Convert and download. Press Convert, then grab each file individually or use Download all.

Which format should you pick?

WebP is the best default for the modern web. It produces much smaller files than JPG or PNG while keeping transparency, and every current browser can display it.

AVIF goes even further on compression and is ideal when file size matters most. Support for creating AVIF still varies between browsers, so the tool falls back gracefully and suggests WebP when needed.

JPG remains the safe, universal choice for photographs without transparency. It is understood everywhere, from email clients to old content systems.

PNG is lossless and keeps sharp edges and transparency intact. It is the right pick for logos, icons, screenshots, and line art.

Why convert in the browser?

Uploading photos to an online converter means handing your images to someone else's server. This tool avoids that entirely by decoding and re-encoding each file locally.

That keeps private photos private, works offline once the page has loaded, and is fast because there is no upload or download round-trip. As a bonus, re-encoding strips embedded EXIF metadata such as GPS coordinates and camera details.

• Private by design: images are processed on your device and never uploaded.
• Modern formats: export to WebP and AVIF for dramatically smaller files.
• Batch friendly: queue many images and convert them in one click.
• Metadata removed: EXIF tags are dropped during conversion.

Converting versus resizing and cropping

Converting changes the format and file size of an image while leaving the picture itself intact. Resizing changes the pixel dimensions, and cropping changes the framing.

If your main goal is to make an image physically smaller in width and height, the Image Resizer is built around that job with percentage scaling and preset social-media sizes. When you need to trim the edges or lock a picture to a specific shape, the Image Cropper handles the framing before you convert.

To check or remove hidden data without changing the format, the EXIF Viewer & Remover reads and strips metadata in place. And when you need an image inlined into HTML or CSS rather than saved as a file, the Image to Base64 Converter turns it into a data URI you can paste straight into your code.

Frequently Asked Questions

Is my image uploaded to a server when I convert it?

No. The conversion runs entirely in your browser using the HTML canvas, so the image is decoded and re-encoded on your own device. Nothing is uploaded, stored, or logged anywhere.

Which formats can I convert between?

You can read JPG, PNG, WebP, AVIF, GIF, and BMP files, and export to WebP, JPG, PNG, or AVIF. WebP and AVIF usually give the smallest files at the same visual quality.

Should I choose WebP or AVIF?

WebP is the safe default because every modern browser can both create and display it. AVIF squeezes files even smaller, but browser support for encoding it varies, so the tool will tell you to switch to WebP if your browser cannot produce it.

Does converting remove EXIF metadata like GPS location?

Yes. Re-encoding through the canvas drops embedded EXIF tags such as GPS coordinates, camera model, and timestamps. If you want to inspect or strip metadata without changing the format, use the dedicated metadata tool instead.

Can I convert several images at once?

Yes. Drop or select multiple files and they are added to a queue, then one click converts them all to the format you picked. Each result gets its own download button, plus a Download all option.

What does the quality slider actually do?

For lossy formats (WebP, JPG, AVIF) it controls the compression trade-off, where a lower value means a smaller file with more visible artefacts. PNG is lossless, so the slider is hidden when PNG is selected.

Will a PNG with transparency survive conversion?

Transparency is kept when you convert to WebP, PNG, or AVIF. Converting to JPG flattens the image onto a white background because the JPG format has no alpha channel.
