Compress files without losing quality
Images, PDFs, video, and audio — up to 500 MB per file. Batch compression supported.
Files are deleted from our servers after your compressed download is delivered.
Lossless and lossy compression with customizable quality. Images, PDFs, videos, and audio files supported.
Select multiple files and compress them in parallel. Download individually or as a combined archive.
Files are deleted immediately after compression. Optional metadata stripping removes EXIF and GPS data.
Why Compress Files Before Sharing?
Smaller file types upload and download faster, use less storage space, and are easier to send. FileShot's online compressor handles images (JPG, PNG, WEBP, TIFF, BMP), PDF files, videos (MP4, MOV, AVI), and audio files (MP3, WAV, OGG). To compress PDFs or images, click Compress after uploading — each supported file type gets format-specific optimization at the quality level you choose.
How Compression Works
Image compression reduces file size by removing data imperceptible to the human eye. A quality level of 70–80% typically achieves a 60–80% size reduction with no visible loss. For an online PDF, FileShot's PDF tools compress internal structure, embedded images, and metadata. Video and audio use codec optimization to lower bitrate while maintaining high quality playback.
All processing happens on FileShot's secure servers. Files are deleted immediately after the compressed output is delivered. You can also strip metadata during compression by enabling the option in the settings, combining two privacy steps into one.
Advanced File Compression
FileShot's file compressor uses industry-leading compression algorithms to reduce file sizes while maintaining quality. Our compressor supports images, documents, videos, and general-purpose files, applying format-specific optimizations that achieve the best possible compression ratios. Whether you need to compress a single large file for email attachment or batch-compress an entire folder of images for web publishing, FileShot handles it directly in your browser with no uploads required.
Image Compression
Our image compressor supports JPEG, PNG, WebP, GIF, and SVG formats. For JPEG images, intelligent quality reduction removes imperceptible visual data while keeping the image looking sharp. PNG compression uses advanced palette optimization and redundancy elimination. WebP conversion can reduce image sizes by up to seventy percent compared to equivalent JPEG files. For web developers and content creators, batch image compression with configurable quality settings makes it easy to optimize entire image libraries in minutes.
Document and Archive Compression
Compress PDF documents, Office files, and text documents to reduce storage requirements and transfer times. Our document compressor optimizes internal structure, removes redundant metadata, downsizes embedded images, and applies text-level compression to reduce file sizes by thirty to sixty percent. Archive compression creates optimized ZIP files with configurable compression levels, allowing you to balance between maximum compression and processing speed based on your specific needs.
Privacy-Preserving Compression
Every file processed by FileShot's compressor remains on your device throughout the entire compression workflow. We do not upload, temporarily store, or cache any file data on our servers. This makes FileShot the ideal compression tool for sensitive documents including medical records, financial statements, legal contracts, and confidential business materials. Combined with our metadata scrubber, you can compress and sanitize files in a single private workflow before sharing them securely through FileShot's encrypted transfer system.
Frequently asked questions
Will compression reduce quality?
You control the quality slider. Levels around 70–80% usually shrink files dramatically with little visible change for photos and PDFs.
What file types can I compress?
Images, PDFs, video, and audio are supported. Each format uses targeted optimization settings.
Do you keep compressed files on your servers?
No long-term storage. Files are removed after the compressed download is delivered.
