How to Compress Images
- 1Drop or select your images — drag files onto the upload zone or click to open the file picker. Supports JPEG, PNG, WebP, GIF, SVG, BMP, TIFF, AVIF, HEIC, and more.
- 2Choose output format and quality — select JPEG, WebP, or PNG from the dropdown, then adjust the quality slider (80–85% is a good starting point for photos).
- 3Download compressed files — each result shows before/after file size. Click Download to save individually.
Which format should I use?
WebP offers the best compression for most web images — typically 25–35% smaller than JPEG at equivalent quality, with browser support above 95%. JPEG is best for photographs and rich imagery where transparency isn't needed. PNG is ideal for graphics, logos, and screenshots with sharp edges or transparency.
How much can images be compressed?
Typical results: JPEG photos at 85% quality are 40–60% smaller than originals. Converting PNG photos to WebP can cut sizes by 60–80%. Results vary by image content — flat graphics compress more than complex photographs.
Is my data safe?
All compression happens entirely in your browser using the Canvas API. Files are never transmitted to any server. This makes LiteBox safe for confidential product shots, medical imagery, or client assets.
Frequently Asked Questions
Lossy formats (JPEG, WebP) do reduce some detail, but quality loss is imperceptible at 80–90% settings for most images. PNG is lossless, so PNG output is never degraded. Always compare the before/after sizes shown in the results panel.
Each file may be up to 12 MB. You can process up to 20 files per session. Very large images (e.g., 50+ MP) may be slow on low-memory devices, since all processing is in-browser.
HEIC/HEIF is supported on Safari (macOS/iOS). AVIF support depends on the browser's Canvas API implementation. On unsupported browsers, an error will be shown for those specific files. Chrome and Edge support AVIF since version 85.
WebP uses a more efficient compression algorithm (based on VP8), supports both lossy and lossless modes, and can include transparency like PNG. For most web images, WebP is 25–35% smaller than equivalent JPEG at the same perceived quality.
Yes — images are often the largest assets on a webpage. Reducing their size directly improves Largest Contentful Paint (LCP) and reduces total page weight, which benefits both user experience and search engine ranking. Google PageSpeed Insights specifically checks for image optimization.
