Adjust quality
Use the quality slider to set your target compression level. The default 80% typically reduces file size by 60-80% with no visible quality difference. Go lower for smaller files, higher for maximum fidelity.

Web developers
Optimize images for faster page loads. Compress product photos, hero images, and thumbnails before deployment. Smaller images mean faster Core Web Vitals and better SEO.
Email campaigns

Social media managers
Batch compress images before scheduling posts. Faster uploads, less storage used, and your followers see the same visual quality.

Reduce image sizes for blog posts and articles. Compressed images load faster, which means lower bounce rates and better reader experience.
Ecommerce stores
Compress product photography in bulk. Lighter images mean faster shop pages, which directly impacts conversion rates and search rankings.
Students and professionals
Shrink images for presentations, reports, and documents. Keep your files under upload limits for email, Google Drive, or LMS platforms.
Frequently asked questions
Is PixelTools image compressor free?
+
Yes, completely free with no limits. Compress as many images as you want, as often as you want. No subscription, no trial, no account required.
Does compressing an image reduce its quality?
+
At the default 80% quality setting, the difference is imperceptible to the human eye while reducing file size by 60-80%. You can adjust the quality slider to find the right balance between size and fidelity for your needs.
Are my images uploaded to a server?
+
No. PixelTools compresses images entirely in your browser using the Canvas API. Your files never leave your device — there is no server upload, no cloud processing, and no data stored anywhere.
What image formats can I compress?
+
PixelTools supports JPG, PNG, and WebP for compression. Need to convert from HEIC, SVG, BMP, TIFF, or AVIF? Use our Image Converter — same engine, more formats.
Can I compress multiple images at once?
+
Yes. Drop or select as many images as you need — they are all compressed in batch. You can download each file individually or all at once.
How is this different from TinyPNG?
+
TinyPNG uploads your images to their server for processing and limits free usage to 20 images per day. PixelTools compresses everything locally in your browser with no upload and no usage limits. Your images stay private.
What is the maximum file size I can compress?
+
PixelTools can handle images up to 50 MB each. Very large images may take a few seconds to process depending on your device, but there is no hard limit on resolution.
Does compression change image dimensions?
+
No. By default, PixelTools preserves the original width and height of your image. Only the file size is reduced. Dimensions stay exactly the same.
