JPG compresses photographs into small shareable files; PNG keeps every pixel and supports transparency for logos, UI, and screenshots. Picking wrong usually means blurry text or oversized photos.

JPG · PNG

JPG and JPEG are the same image format — only the filename extension differs. MIME type is image/jpeg either way. This page exists so searchers get a clear answer instead of a fake “versus.”

JPG · JPEG

JPG is the universal photo currency; WebP usually delivers smaller files at similar quality for modern websites and can include transparency JPEG cannot.

JPG · WEBP

JPG remains the safest photo exchange format; AVIF often wins on compression for modern sites using AV1 stills, with younger tooling and fallback needs.

JPG · AVIF

PNG is the lossless, universally understood choice for UI and screenshots. WebP usually produces smaller files in lossy or lossless modes and still supports alpha.

PNG · WEBP

PNG is the lossless UI workhorse; AVIF targets much smaller modern-web delivery (including alpha) with slower encodes and legacy fallback needs.

PNG · AVIF

WebP is the widely deployed next-gen web image format; AVIF often compresses photographs further using AV1, with slightly younger tooling and encode-time tradeoffs.

WEBP · AVIF

HEIC is Apple’s efficient camera original; JPG is the universal photo exchange format. HEIC saves space on iPhone; JPG arrives intact for Windows users, older apps, and most websites.

HEIC · JPG

HEIC is an efficient camera/photo container; PNG is a lossless graphics format with alpha. They solve different jobs — photo libraries versus UI-sharp images.

HEIC · PNG

HEIC optimizes on-device photo libraries (especially Apple). WebP optimizes web delivery in browsers. Convert HEIC→WebP when publishing phone photos to modern sites.

HEIC · WEBP

TIFF is a high-quality scan/print/archival raster; JPG is the everyday share format. TIFF preserves detail; JPG shrinks photos for the web and chat.

TIFF · JPG

BMP stores simple uncompressed (or lightly packed) bitmaps; JPG compresses photos for real-world sharing. BMP files are easy to decode and enormous.

BMP · JPG

SVG is resolution-independent vector markup for logos and icons; PNG is a pixel grid with optional alpha. SVG scales forever; PNG is a snapshot at one resolution.

SVG · PNG

SVG describes shapes as math; JPG compresses photographs as pixels. They are not interchangeable — SVG is wrong for photos, JPG is wrong for scalable logos.

SVG · JPG

MP4 is the cross-platform delivery container; MOV is Apple’s QuickTime container common for iPhone footage and pro intermediates. Codecs often overlap — ecosystem fit matters most.

MP4 · MOV

MP4 prioritizes universal playback; MKV prioritizes flexible tracks — multiple audio languages, subtitles, and chapters for archival rips.

MP4 · MKV

MP4 (usually H.264/AAC) is the safest universal video delivery format. WebM targets open web codecs (VP8/VP9/AV1 + Opus) for HTML5-centric pipelines.

MP4 · WEBM

AVI is a legacy Windows multimedia container with unpredictable codecs inside; MP4 is the modern default for phones, web, and social.

AVI · MP4

MOV is Apple’s QuickTime-oriented container; AVI is a legacy Windows container. Neither is the friendliest modern delivery default compared with MP4.

MOV · AVI

M4V is an Apple-oriented MP4-family video file. Unprotected M4V is often essentially MP4; some store titles were DRM-wrapped.

M4V · MP4

MP3 is compressed for everyday listening and podcasts; WAV is usually uncompressed PCM for editing and masters.

MP3 · WAV

MP3 discards audio data to shrink files; FLAC compresses without losing samples.

MP3 · FLAC

AAC usually sounds better than MP3 at the same bitrate and powers much of Apple/YouTube audio. MP3 still wins raw compatibility on older hardware.

AAC · MP3

M4A usually wraps AAC (sometimes ALAC) and fits Apple voice memos and music. MP3 remains the most recognized audio extension worldwide.

M4A · MP3

WAV is typically uncompressed PCM — simple and huge. FLAC is lossless but smaller, with richer tagging for music libraries.

WAV · FLAC

OGG with Vorbis/Opus is an open, efficient choice in FOSS and some web audio; MP3 remains the compatibility king for offline hardware.

OGG · MP3

Opus outperforms older codecs at low bitrates for speech and holds up well on music; MP3 is easier to send to people who will never install a specialty player.

Opus · MP3

ALAC and FLAC are both lossless. ALAC fits Apple libraries (often in M4A); FLAC is the open favorite for cross-platform enthusiast archives.

ALAC · FLAC

AIFF is Apple’s classic uncompressed audio; WAV is the more universal PCM exchange format on Windows and most DAWs.

AIFF · WAV

DOCX is for drafting and collaboration; PDF is for fixed layout, signatures, and distribution.

PDF · DOCX

DOC is the legacy binary Word format; DOCX is the modern Office Open XML standard. Same job — drafting — different packaging and compatibility.

DOC · DOCX

RTF is an older cross-platform rich-text format with basic styling. DOCX is the modern Word standard with stronger layout, styles, and collaboration features.

RTF · DOCX

ODT is the OpenDocument editable text standard (LibreOffice). DOCX is Microsoft’s default. Both are editable — ecosystems differ.

ODT · DOCX

XLS is legacy binary Excel; XLSX is the modern default. Prefer XLSX for new work and convert old XLS archives when sharing.

XLS · XLSX

PPT is legacy PowerPoint; PPTX is the modern presentation package. Same purpose — different compatibility and media handling.

PPT · PPTX

ZIP is the universal folder-sharing archive. RAR often compresses document trees better and supports recovery records, but creation tooling is less ubiquitous.

ZIP · RAR

ZIP maximizes who can open your archive. 7Z often maximizes compression on source trees and documents using LZMA.

ZIP · 7Z

Both chase high compression. RAR is proprietary with strong multi-volume/recovery features; 7Z is an open LZMA-based format popular with 7-Zip users.

RAR · 7Z

TAR bundles files for Unix pipelines (often plus gzip). ZIP combines packaging and compression in a Windows/macOS-friendly package.

TAR · ZIP

GZIP (GZ) compresses a single stream and shines on Unix beside tar. ZIP bundles many files with broad double-click support.

GZ · ZIP

ZIP bundles multiple files for mainstream desktops. GZ compresses one stream and is native to Unix toolchains (often with tar).

ZIP · GZ

CSV is a plain-text table for interchange; XLSX is a full Excel workbook with sheets, formulas, and formatting.

CSV · XLSX

JSON is the default for modern web APIs; XML still dominates document standards, feeds, and enterprise schemas.

JSON · XML

CSV is a flat table; JSON can nest objects and arrays. Convert cleanly only when JSON is an array of uniform objects.

CSV · JSON

CSV uses commas; TSV uses tabs. Both are plain-text tables — TSV avoids comma collisions; CSV is what most Export buttons emit.

CSV · TSV

TXT is plain characters with no formatting. DOCX adds styles, images, tables, and commenting for real documents.
