How to Compress Images Online Without Losing Quality (JPG, PNG, WebP)
Large photos slow down websites, fill email attachments and eat up phone storage. An image compressor makes pictures smaller while keeping them looking good. This free image compressor and converter shrinks JPG, PNG and WebP files in your browser, and your photos never leave your device.
Why you need a image compressor
- Photos from modern phones can be several megabytes each.
- Big images make web pages load slowly, which hurts visitors and search rankings.
- Email and upload forms often have file-size limits.
- You may need a different format, such as WebP or JPG, for a website or app.
Common problems when looking for a image compressor
- Many online compressors upload your photos to a server, which is a privacy risk.
- Some limit the number of files or the file size on the free plan.
- Aggressive compression leaves blocky, blurry results.
- It’s unclear which format and quality setting is best.
- Re-saving can leave behind hidden data such as location.
How this free image compressor solves the problem
- Compression happens entirely in your browser, so photos stay private.
- Compress up to 20 images at once and see the size saved for each.
- Convert between JPG, PNG and WebP.
- Set a quality level and an optional maximum width to shrink large photos further.
- Saving through the browser removes camera and location metadata.
Do’s and don’ts of using a image compressor
Do
- Start with a quality around 70 to 80 and compare the result.
- Use WebP or JPG for photos, and PNG for logos, icons and screenshots.
- Set a maximum width, such as 1600 px, for images shown on websites.
- Keep your original files in case you need to edit them later.
Don’t
- Don’t compress the same JPG again and again, because quality drops each time.
- Don’t convert a transparent PNG to JPG if you need to keep the transparency.
- Don’t set quality too low for photos with fine detail or text.
- Don’t resize images larger than their original size.
Tips for reducing image file size
- Smaller images help your pages load faster, which visitors and search engines both like.
- WebP is often noticeably smaller than JPG at similar quality and is widely supported by modern browsers.
- Name files clearly before uploading, for example “red-running-shoes.webp”.
- Compress screenshots as PNG only when sharp text matters. Otherwise try WebP.
- Always check the result at full size before replacing the original.
Frequently asked questions
Are my photos uploaded?
No. Compression happens in your browser, so your images never leave your device.
Which format gives the smallest file?
WebP is usually smallest, then JPG. PNG is lossless, so it saves the least and works best for logos and screenshots.
Does it remove photo data?
Yes. Re-saving through the browser drops metadata such as camera details and GPS location, which is good for privacy.
Will quality drop?
A little, depending on the quality slider. Values around 70 to 80 usually look nearly identical while saving a lot of space.
