About Image Compressor
Our free image compressor lets you reduce image file sizes without sacrificing visual quality. Get a phone photo light enough for a blog post, a product shot under a marketplace upload cap, or a screenshot small enough for an email attachment: pick a quality level and output format, then compress images online and compare the before and after file sizes side by side. Your files are never uploaded.
Large image files slow down web pages, eat up storage space, and frustrate users on slower connections. An efficient image compression tool solves these problems by intelligently shrinking file sizes while keeping images looking sharp. You can choose between JPEG, PNG, and WebP output formats and fine-tune the quality slider to find the perfect balance between size and clarity.
This online image compressor is ideal for web developers, photographers, bloggers, e-commerce managers, and anyone who works with images regularly. With support for adjustable quality, custom maximum dimensions, and aspect-ratio preservation, you have full control over the final result every time.

Frequently Asked Questions
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.
