Compress Image Online

How to compress an image

1. 1

   Add your image

   Drag a JPG, PNG or WEBP file into the box above, or click to browse. Photos, screenshots and graphics all work.

2. 2

   Choose a quality level

   Drag the quality slider to set how hard the compressor works. 80% is a good starting point: high enough to keep detail, low enough to remove most of the file size.

3. 3

   Download the result

   Press Compress Image. The result appears with its new file size and the percentage saved, ready to download — or try another quality setting first.

Which quality setting to use

A rough guide. The result card always shows the exact size before you download, so it is worth trying two settings.

When you need a smaller image file

• Making a website faster

  Images are usually the largest thing a page downloads. Compressing them improves Largest Contentful Paint, the Core Web Vital Google measures loading speed with.

• Getting under an upload limit

  Job applications, visa portals, school systems and government forms routinely cap uploads at 1 MB or 2 MB. A phone photo is several times that.

• Sending photos by email

  Most providers reject messages over 20–25 MB. Compressed photos fit in one message instead of three.

• Saving storage and bandwidth

  Batches of screenshots, receipts and scans take a fraction of the space once re-encoded — on your drive and in your backups.

Frequently asked questions

Does compressing an image reduce its quality?

Technically yes — JPG and WEBP are lossy formats, so some detail is discarded. In practice, at 80% quality the difference is invisible at normal viewing size on almost any photograph. Pixel dimensions are untouched: a 4000 × 3000 image stays 4000 × 3000, only the file gets lighter.

How do I compress an image to a specific size, like 100 KB or 1 MB?

Lower the quality slider and press Compress Image — the result card shows the exact size you would download. Repeat until you are under your target. If quality alone cannot get you there, the image is probably far larger than it needs to be in pixels, so resize it first and then compress.

Are my images uploaded to a server?

No. Compression happens inside your browser tab using the Canvas API. Nothing is sent anywhere, there is no queue, and the tool keeps working if you lose your connection after the page has loaded.

Is there a limit on how large an image I can compress?

No limit is imposed by the tool. The practical ceiling is your device's memory, and images up to 16,384 pixels on a side are supported.

Can I compress a PNG?

Yes. PNG uses lossless compression, so re-saving it as a PNG would change nothing — the tool saves it as WEBP instead, which keeps transparency and responds to the quality slider. Expect a considerably larger saving than a PNG optimiser would give you.

Does it add a watermark?

No. Nothing is drawn onto the image and no account is required. What you download is your image at a smaller file size.

Will compressing remove EXIF data like GPS location?

Yes. Re-encoding produces a fresh file with no metadata, so camera details, timestamps and GPS coordinates are gone. That is usually a benefit before posting a photo publicly.

Can I compress HEIC photos from an iPhone?

The compressor takes JPG, PNG and WEBP. For a HEIC photo, run it through the HEIC to JPG converter first, then compress the JPG here. HEIC is already an efficient format, so the conversion itself usually makes the file bigger — compressing afterwards brings it back down.
