Browser-local image lab

DPI metadata is not image quality. Changing 72 DPI to 300 DPI does not add pixels or sharpness.
Choose your target format and adjust the quality slider to find the perfect balance between size and clarity.
Select or drag and drop your images into the conversion zone. We support JPG, PNG, WebP, AVIF, and more.
Conversion happens instantly in your browser. Download individually or grab everything as a convenient ZIP file.
Unlike other converters, we don't upload your files to our servers. All processing is done client-side.
Each image is converted with the Canvas API on your device, one file at a time.
Stay ahead of the curve with support for next-gen formats like WebP and AVIF for better web performance.
There is no daily quota. Images wider or taller than 16,384 pixels, or over 80 million pixels, are skipped so the tab stays stable.
Add several images, convert them in order, then download each file or a ZIP of the results.
The slider affects JPEG, WebP, and AVIF. PNG output stays lossless. Animated files keep the first frame only.

Most people do not want “a bit smaller”. They need ≤ 200 KB because a form said so. This page searches quality, then reduces pixels if the floor is still too big. The generic Compress Image tool also has a target field; this URL is for the 200 KB intent.
PNG is lossless. A 2000 px screenshot may never become 200 KB as PNG. The compressor then writes JPEG (or your chosen WebP/AVIF) and notes that the format changed. Transparency is flattened on JPEG.
Evaluate compression ratio, quality behavior, and browser support before choosing a format.
WebP usually delivers smaller files, while PNG remains a strong choice for pixel-perfect assets. Use this comparison to choose the right format by scenario.
JPEG is still the universal photo format, but WebP usually wins on bytes for the same perceived quality. Use this comparison to decide when to convert and when to keep JPEG.
AVIF often compresses further than WebP, while WebP still wins on tooling and encode speed. Use this comparison when choosing a modern delivery format.
Practical tutorials for conversion workflows, SEO optimization, and CMS delivery.
This guide shows how to migrate PNG-heavy assets to WebP while preserving quality, transparency, and rollout safety across multilingual pages.
Image SEO is more than compression. Rankings and Core Web Vitals improve when format, dimensions, naming, alt text, delivery, and internal linking work together.
WordPress sites usually need more than one format. This guide maps each content type to a reliable format strategy.
