File formats: what to choose

A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.

🖼️

Images

Raster and vector graphics for web, print, and photography.

Common extensions: PNG, JPG, WebP, AVIF, GIF, SVG, HEIC, TIFF

Advantages

+ WebP and AVIF offer excellent compression for the web
+ PNG keeps transparency and sharp edges
+ SVG scales without quality loss

Disadvantages

− RAW and TIFF files are large and slow to share
− JPEG loses quality on every re-save
− Some formats are not supported in older browsers

🎵

Audio

Music, podcasts, voice recordings, and sound effects.

Common extensions: MP3, WAV, FLAC, OGG, AAC, M4A, OPUS

Advantages

+ FLAC and WAV preserve full quality for editing
+ MP3 and AAC are universally compatible
+ OPUS delivers great quality at low bitrates

Disadvantages

− Uncompressed WAV files are very large
− Lossy formats cannot be restored to original quality
− DRM-protected files may not convert

🎬

Video

Clips, streams, screen recordings, and movies.

Common extensions: MP4, WebM, MOV, MKV, AVI, MPEG

Advantages

+ MP4 (H.264/H.265) plays almost everywhere
+ WebM is efficient for web embedding
+ MKV can hold multiple audio and subtitle tracks

Disadvantages

− High-resolution video needs lots of storage and bandwidth
− Re-encoding always takes time and may reduce quality
− Some codecs require licensing for commercial use

📄

Documents

Office files, PDFs, ebooks, and plain text.

Common extensions: PDF, DOCX, XLSX, PPTX, ODT, EPUB, TXT

Advantages

+ PDF locks layout for printing and sharing
+ DOCX and ODT are easy to edit collaboratively
+ Plain text works on any device

Disadvantages

− PDF is hard to edit without special tools
− Complex layouts may shift after conversion
− Scanned PDFs need OCR for editable text

📦

3D models

Meshes and scenes for 3D printing, games, and CAD.

Common extensions: OBJ, STL, GLTF, GLB, FBX, PLY

Advantages

+ STL is standard for 3D printing
+ GLTF/GLB is optimized for the web and AR
+ OBJ is widely supported in 3D software

Disadvantages

− File size grows quickly with detail
− Materials and animations may not transfer
− Some formats lack units or scale metadata

🗜️

Archives

Compressed bundles of files and folders.

Common extensions: ZIP, 7Z, RAR, CAB, ARJ

Advantages

+ ZIP opens natively on most operating systems
+ 7Z achieves very high compression ratios
+ Archives simplify bulk downloads and email attachments

Disadvantages

− Password-protected archives need the correct password
− RAR may require extra software on some systems
− Corrupted archives cannot be fully recovered

📦

TAR & Unix compression

Tape archives and layered compression common on Linux, macOS, and servers.

Common extensions: TAR, GZ, TGZ, BZ2, XZ, ZSTD

Advantages

+ TAR preserves Unix permissions and folder structure
+ GZ, XZ, and ZSTD offer strong compression for backups
+ Standard format for software packages and server deploys

Disadvantages

− Windows needs extra tools to open TAR without conversion
− Double extensions like .tar.gz can confuse some users
− Solid compression makes partial extraction slower

🔤

Fonts

Typefaces for websites, design, and documents.

Common extensions: TTF, OTF, WOFF, WOFF2

Advantages

+ WOFF2 is ideal for fast web loading
+ OTF supports advanced typography features
+ TTF works across desktop apps

Disadvantages

− License restrictions may limit conversion or embedding
− Hinting can differ between formats
− Variable font axes may be lost in conversion

💬

Subtitles

Timed text tracks for video accessibility.

Common extensions: SRT, VTT, ASS, SSA

Advantages

+ SRT is simple and widely supported
+ VTT is the web standard for HTML5 video
+ ASS/SSA support styling and effects

Disadvantages

− Timing may drift after video re-encoding
− Styled subtitles may flatten when converted to SRT
− Multi-language tracks need separate files
