Frequently asked questions
How much can compression shrink my files?
Photos: 60–80%. PDFs: 30–70% depending on embedded images. Videos: 40–70% with our smart re-encoding presets.
Will compression hurt visible quality?
At default settings the difference is nearly invisible. Push the quality slider lower for smaller files, higher to preserve every detail.
Are my files uploaded anywhere?
Image and PDF compression run entirely in your browser. Video compression may use a transient processing service for heavy formats; nothing is stored.
Can I compress files in batch?
Yes — every compress tool supports multi-file upload and a single ZIP download.
Why does compressing matter for SEO?
Smaller files load faster, which directly improves Core Web Vitals (LCP, INP) and Google's page-experience signals — a measurable ranking lift.
What's the best image compression for web pages?
Use WebP at quality 78–82 for photos, PNG for sharp graphics. Aim for hero images under 200 KB and content images under 100 KB.
How do I compress a PDF for email?
Use the Compress PDF tool with the 'Email' preset — it targets <10 MB by downsampling embedded images and re-encoding fonts.
Can I compress a video for WhatsApp or Instagram?
Yes. Pick the social preset in Compress Video — it outputs H.264 MP4 at 1080p or 720p, ideal for messaging and feeds.
Does compression remove EXIF and metadata?
Yes by default, which protects your privacy. Use our EXIF Stripper to remove metadata without re-encoding the image.
What file size should I target for product photos on Shopify or WooCommerce?
Aim for 80–150 KB per product image at 1200–2000 px on the long edge — large enough for retina but small enough for fast load times.
Why is my PDF still big after compression?
Embedded high-resolution images dominate PDF size. Use the 'Aggressive' preset or split the PDF and compress image-heavy pages individually.
Can I compress files on mobile?
Yes — all tools are mobile-friendly. iPhone HEIC and Android HEIF photos are decoded in the browser.
What's the difference between lossless and lossy compression?
Lossless keeps every bit (PNG, ZIP) — small savings, perfect quality. Lossy (JPG, WebP, MP4) discards imperceptible data — big savings, visually similar.
Will Google penalize compressed images?
No — Google explicitly recommends compression. Smaller, optimized images rank better because they improve user experience and Core Web Vitals.
Can I undo compression?
No — lossy compression is one-way. Always keep the original file safe; only the compressed copy is reduced in quality.
