Frequently Asked Questions — Image Compression

Enable the "Target size" toggle and enter 20 as the KB target. Our binary search algorithm will automatically find the right quality level (typically 30–50%) to hit exactly under 20KB. Works for JPEG, WebP, and AVIF.
Use the Target size field — type 50 or 100 (KB) and the tool auto-adjusts quality. Most photos can hit 100KB with quality 70–80% looking nearly identical to the original. For 50KB, you may need to also resize to ~800px width.
Three proven techniques: (1) Convert to WebP or AVIF — modern formats save 30–60% with no visible quality loss. (2) Use quality 80–85% for JPEG — humans can rarely tell the difference vs 100%. (3) Strip EXIF metadata to save another 5–50KB. Combine all three for maximum lossless-feeling compression.
Many government and visa application forms require photos under 200KB. Set the Target size to 200, keep format as JPEG (most forms require it), and enable Strip metadata. Done in under 2 seconds.
Use our YouTube Thumbnail preset (1280×720) with WebP at quality 85%. YouTube limits thumbnails to 2MB, but you'll typically end up at 100–300KB while keeping text crisp. Browse "More sizes..." for all platform presets.
Discord limits free uploads to 25MB and inline embed previews to ~8MB. Use the "Web Optimized" preset or set quality to 75%. For screenshots, try WebP — preserves text quality at half the size of PNG.
Yes — for most photos, quality 80–85% is perceptually identical to 100% but saves 50–70% file size. Convert to AVIF format for the largest savings (up to 80% smaller than original JPEG) while still looking pristine.
Input: JPEG, JPG, PNG, WebP, GIF. Output: JPEG (with MozJPEG encoder for better compression), PNG, WebP, AVIF (Chrome 85+, Safari 16+, Firefox 93+, Edge 121+).
AVIF is a modern image format from 2019 that compresses 50–60% smaller than JPEG at the same visual quality. Use it for modern web — falls back to WebP/JPEG for older browsers automatically.
No. 100% local processing happens in your browser. Your images never leave your device — unlike TinyPNG or Compressor.io which upload to their servers. Works offline once the page is loaded.
Yes — drag and drop up to 10 images for quick batch compression. Download all as ZIP. For larger batches (50+), use our Bulk Image Compressor tool.
Use the "Web Optimized" preset: WebP format at 80% quality, max 1920px width, EXIF stripped. This typically reduces 5MB photos to 200–400KB — perfect for Core Web Vitals and PageSpeed scores. Better than ShortPixel image optimizer because it's free and processes locally.
Quality compression alone keeps dimensions the same. To reduce both file size AND pixel dimensions, use the Resize section: type custom width/height or pick a preset (Instagram, YouTube, Facebook, etc.). Lower resolution + lower quality = smallest file.
Removes EXIF data (camera model, GPS coordinates, timestamps) from your image. Reduces file size by 5–50KB and protects your privacy when sharing photos online — especially important if you're sharing photos taken on your phone.
Yes — completely free with no signup, no watermark, no daily limits. We compress unlimited photos for unlimited users because all the work happens in your browser, not on our servers.
