Why Do You Need a File Resizer?

Email attachments often have size limits (Gmail: 25MB, Outlook: 20MB). Large images or PDFs can get blocked. File compressors reduce file size while keeping acceptable quality. Our curated tools help you compress images, PDFs, and documents quickly – no software installation needed.

Common File Size Limits

Email attachments: 20-25 MB (most providers).
WhatsApp images: Auto-compressed, but original size may exceed 5MB.
Website uploads: Many forms limit to 2-5 MB.
Cloud storage (free tier): 15GB (Google Drive), 5GB (OneDrive).

How Much Can You Compress?

JPG images: 60-80% reduction (quality barely visible).
PNG images: 30-50% reduction (lossless).
PDFs (scanned): 50-70% using downsampling.
PDFs (text-based): 20-30% reduction.

Best Practices

Keep a copy of original file before compressing.
For social media, compress to 1-2 MB – good enough for viewing.
For printing, use minimal compression or keep original.
PDF compression is best for reducing email attachment size.

Lossy vs Lossless Compression

Lossy (JPG, some PDFs) removes data to shrink file size – you lose some quality. Lossless (PNG, ZIP) keeps all data but achieves less reduction. Our recommended tools default to a balanced setting.
