Compression Tips

• JPEG: Best for photos with many colors. Quality setting affects file size and image quality

• PNG: Best for images with transparency or few colors. Quality setting is ignored

• WebP: Modern format with excellent compression. Supported by most modern browsers

• Lower quality = smaller file size but reduced image quality

• Reducing dimensions significantly decreases file size

• All processing happens in your browser - images are never uploaded to servers

Frequently Asked Questions

Is this image compressor free to use?

Yes, the tool is completely free with no sign-up required. There are no watermarks added to your compressed images and no daily usage limits.

Is my data secure?

Absolutely. All compression happens directly inside your browser using the HTML5 Canvas API. Your images are never uploaded to any external server, so your data stays fully private.

What file formats are supported?

You can upload JPG, PNG, and WebP images. The tool also lets you convert between these formats during compression, for example compressing a PNG and saving it as a WebP.

How much can I reduce my file size?

Results depend on the image content and settings, but typical JPEG compression at 70-80% quality reduces files by 40-70% with minimal visible quality loss. WebP often delivers even greater savings.

Does compression affect image quality?

At moderate quality levels (70-90%), the difference is virtually invisible to the human eye. Lower settings produce smaller files but may introduce noticeable artifacts. Use the side-by-side preview to find the sweet spot.

Can I also resize images while compressing?

Yes. Set a maximum width and height in the settings panel. Reducing dimensions is one of the most effective ways to shrink file size further.

Tips & Best Practices

Start at 80% quality: This is usually the best trade-off between size reduction and visual fidelity for JPEG images.
Use WebP for the web: WebP provides the smallest files with excellent quality and is supported by all modern browsers.
Keep PNG for transparency: Choose PNG output if your image requires a transparent background; use JPEG or WebP otherwise.
Resize before compressing: Reducing maximum dimensions first yields the largest file-size savings.
Compare before downloading: Always review the side-by-side preview to ensure the compressed image meets your quality standards.
Lock aspect ratio: Keep the aspect-ratio checkbox enabled to avoid stretching or squishing your images during resizing.
