Lower = smaller file. 75 is a safe default for photos.

Resizing the longest edge often shrinks files dramatically.

How to compress images

Three steps to smaller pictures — entirely inside your browser.

  1. Add your images

    Drag up to 30 images into the drop zone, click to pick files, or press ⌘V / Ctrl+V to paste from the clipboard. JPEG, PNG, WebP and AVIF are all accepted.

  2. Adjust quality

    The default quality of 75 removes 60–80% of file size with no visible difference. Slide lower for maximum compression or higher to preserve more detail. The output size updates live.

  3. Download the results

    Use the before/after slider to compare, then save each file or grab them all at once. No watermark, no daily limit.

Why use this image compressor

Runs in your browser
Your images are decoded, re-encoded and downloaded on your own device. Nothing is uploaded to a server, so there is no privacy risk and no file-size cap.
Smart quality defaults
The default quality of 75 hits the sweet spot between file size and visual fidelity for most photos. Fine-tune with the slider when you need to.
Batch processing
Drop up to 30 files at once. Each is compressed at your chosen quality and ready to download individually or as a batch.
Live before/after preview
Slide between the original and compressed version to verify quality before you save. No guessing, no surprises.
All major formats
Accepts JPEG, PNG, WebP and AVIF on input. Output as JPEG for broad compatibility or switch to WebP for an extra 25–35% saving.
Works offline
Once the page has loaded, the compressor keeps working even if you lose your internet connection.

Frequently asked questions

What image formats does this compressor support?
It accepts JPEG, PNG, WebP and AVIF on input. The default output is JPEG; you can switch to WebP for an additional 25–35% reduction at the same perceived quality.
How much will my image shrink?
A typical phone photo at quality 75 drops by 60–90%. The exact saving depends on the image content, resolution, and how much it was already compressed. The live preview shows the result before you download.
Are my images uploaded to a server?
No. Every step — decoding, re-encoding, downloading — happens inside your browser. Your files never leave your device.
Is there a file-size or daily limit?
No. Because nothing is uploaded, there is no per-image cost. Compress as many files as you want, as often as you want, with no cap on input size.
Can I compress multiple images at once?
Yes. Drop up to 30 files in one go. Each is processed at your chosen quality. Use the Download All button to save every result at once.
Will the compressor add a watermark?
No. The output is your image and nothing else — no watermark, no logo, no metadata injection.
Does it work on my phone?
Yes. The tool runs in any modern browser — Chrome, Safari, Firefox, Edge — on any device. Tap the upload area to pick photos from your gallery.
What is the best quality setting?
For most photos, 70–80 gives a major size reduction with no visible difference. Below 50 you may notice artifacts in gradients and fine detail. Above 90 the file barely shrinks. The live preview lets you judge before downloading.

A fast, private image compressor

Most online image compressors upload your files to a remote server, process them there, and send the result back. That round-trip adds latency, raises privacy concerns, and often comes with daily limits or watermarks.

This compressor takes the opposite approach. It uses the HTML5 Canvas API to decode, re-encode, and size your image entirely on your device. The file never leaves your browser tab.

The result is instant feedback, zero privacy risk, and no cap on how many images you process or how large they are.

Your images stay on your device

This tool processes every file locally using the Canvas API. Nothing is uploaded, stored, or analysed on a server. It keeps working even if you go offline after the page has loaded.
