Large image files slow down websites, fill up storage and get rejected by upload limits. Compressing them makes them dramatically smaller while keeping them looking good — but you should not have to send private photos to a random website to do it.
This free image compressor shrinks JPG, PNG, WebP and HEIC images right in your browser. Adjust the quality, watch the file size drop, and download — your photos never leave your device.
How to use it
- 1
Add your image
Drop in a photo or click to choose one. JPG, PNG, WebP and HEIC are all supported.
- 2
Set the quality
Use the slider to choose how much to compress. Lower quality means a smaller file; you can preview the result before saving.
- 3
Download the smaller file
See the before-and-after size and download your compressed image.
Why use this tool
Big size savings
Typical photos shrink by 50–80% with little visible difference, making them much faster to upload and load.
You control the trade-off
A quality slider lets you decide exactly how much to compress for your use case.

How image compression works
Photographs contain far more detail than the eye needs at normal viewing sizes. Compression removes that redundant detail — most aggressively in areas your eye is least sensitive to — so the file gets much smaller while looking almost identical. The right setting depends on the job: 80–90% quality is great for anything you will look at closely, while 60–70% is fine for thumbnails, email and fast-loading pages. Because you can preview the result, you can push it as far as looks acceptable to you.
When to compress
Compress before uploading to a website or blog to speed up page loads and improve SEO, before emailing so attachments send quickly, and before posting where there are file-size limits. Compressing also saves cloud and phone storage. For graphics with sharp edges or text, keep quality high or use PNG; for regular photos, JPG or WebP compress beautifully.
Private by design — nothing is uploaded
Unlike most online converters that send your files to a remote server, this tool does all of its work directly inside your web browser. Your image, video or audio never leaves your device, there is nothing to delete afterwards, and there is no account to create. That makes it faster (no upload or download round-trip on top of the processing) and far safer for anything personal or client-confidential. When you close the tab, everything is gone.
Tips & best practices
- Compress before uploading to a blog or website — smaller images load faster and directly help your page-speed and SEO.
- For email attachments, compressing photos keeps you under size limits and makes messages send instantly.
- Use 80–90% quality for images people will view closely, and 60–70% for thumbnails, avatars and previews.
- Preview the result before downloading so you can push compression as far as still looks good to you.
- Compressing also frees up phone and cloud storage without deleting any photos.
- For graphics with text or sharp edges, keep quality high or use PNG, which handles hard edges better than heavy JPG compression.
Frequently asked questions
How much smaller will my image get?+
It depends on the photo and the quality you choose, but 50–80% smaller is common for typical photographs with no obvious loss in quality.
Will compression make my image blurry?+
At high quality settings the difference is invisible. Only very low settings introduce visible artifacts, and you can preview before downloading.
Can I compress PNG images?+
Yes. For photos, converting to JPG or WebP usually gives a much smaller file; PNG is best kept for graphics and transparency.
Is it free and unlimited?+
Yes — free, no watermark, no sign-up and no limit on the number of images.
Are my photos uploaded?+
No. Compression runs entirely in your browser, so your images stay on your device.

That makes them fast, safe for client and personal files, and usable even on flaky connections once the page has loaded.
We build these because the day-to-day of content creation is full of small friction — converting a file, trimming a clip, resizing an image, cleaning metadata, grabbing a thumbnail.
