It reduces the number of bytes your image needs—by removing redundant data and encoding pixels more efficiently. Compression changes file size, not necessarily pixel dimensions (unless you also resize).
Shrink PNG, JPG, and WebP without the blur. Use the quality slider or target size (KB) to keep images sharp and lean.
Lighter images boost Core Web Vitals and conversions. Optimize hero banners, product shots, and blog graphics in seconds.
Drag a whole folder or select multiple files. The in-browser queue chews through big batches smoothly.
Compression runs locally in your browser. We don’t upload, track, or store your files—ever.
Pick JPG for photos, PNG for graphics with transparency, or WEBP for the smallest size in most cases—preview before saving.
No sign-ups or watermarks. Compress and download as much as you like—fast, reliable, and always free.
Quick answers about formats, quality, SEO, privacy, and getting the smallest files with great visual results.
It reduces the number of bytes your image needs—by removing redundant data and encoding pixels more efficiently. Compression changes file size, not necessarily pixel dimensions (unless you also resize).
Tip: Try WEBP first, fall back to JPG (photos) or PNG (flat graphics).
Compressing reduces file size at the same pixel dimensions. Resizing changes the pixel dimensions (e.g., 4000×3000 → 1600×1200). Combining both gives the biggest savings.
Lossy compression (JPG/WEBP) trades some detail for smaller files. In practice, a quality setting around 70–85 for JPG (or comparable WEBP quality) looks visually identical for most web uses. Always preview before saving.
Yes—by default the in-browser process removes most metadata for a smaller, privacy-friendly result. That means faster loads and no hidden GPS data in published images.
Everything runs locally in your browser. We don’t upload, store, or see your files. Close the tab and they’re gone.
Yes. Drag in a whole folder or select multiple files—the queue processes them in your browser and lets you download the results together.
PNGs are lossless and keep every pixel—great for crisp UI and transparency, but often heavy for photos. Try converting to WEBP (keeps transparency) or to JPG if you don’t need transparent backgrounds.
There’s no one number, but as a rule of thumb: icons/avatars < 50–80 KB, content images 60–200 KB, full-width hero 150–350 KB (modern formats). Resize to display dimensions first, then compress.
