100% Private Processing
Your image is compressed entirely inside your
browser using the HTML5 Canvas API. No file is ever uploaded to any server. Your
images never leave your device.
Why Image Compression Matters: Speed, SEO, and User Experience
Image files are typically the largest assets on any web page, often accounting for 60–80% of
total page weight. Unoptimized images slow down page load times, negatively impact Google
Core Web Vitals scores, consume mobile data budgets, and frustrate users. Compressing images
before uploading them to your website, social media, or email campaigns is one of the
highest-impact optimizations available to content creators.
JPEG vs. PNG vs. WebP: Which Format to Use?

WebP provides 25–35% smaller file sizes than equivalent JPEG/PNG images at equivalent
quality. It is supported by all modern browsers (Chrome, Firefox, Edge, Safari 14+). For
maximum compatibility with older browsers, JPEG remains the best choice for photos.
Frequently Asked Questions
Your images are 100% processed locally in your browser
using the HTML5 Canvas API. No image data is ever sent to our servers. We have
no ability to access, view, or store your images. This makes our compressor safe
to use with sensitive documents, private photos, and confidential screenshots.
For web images (blog posts, social media, product
pages): 70–80% quality typically provides the best balance between file size and
visual quality with minimal visible degradation. For print-quality output:
85–95%. For thumbnails and preview images: 55–65%. Always compare the preview
side-by-side before downloading, as the optimal setting depends on the specific
image content.
PNG uses lossless compression — it preserves every
pixel exactly as in the original, making it ideal for logos, text, and graphics
with sharp edges. JPEG uses lossy compression — it selectively discards
imperceptible visual data, achieving much smaller files but with minor quality
degradation. If your source image is a photograph, export as JPEG or WebP. If it
has transparency or sharp text/line art, use PNG.
