Every conversion Morphr can do

PNG vs WebP: which should you use?

WebP matches PNG’s lossless quality and transparency, then adds a lossy mode that’s 25–35% smaller. Here’s when PNG is still the safer choice.

JPG vs PNG: which one should you use?

JPG compresses photos small by discarding detail; PNG keeps every pixel and adds transparency. When to use each, and what converting actually does.

JPG vs WebP: which gives better quality?

WebP is usually 25–35% smaller than JPEG at the same quality. Here’s why, what you lose converting, and when JPEG is still the safer choice.

AVIF vs WebP: Which Next-Gen Image Format Should You Use?

AVIF usually compresses smaller than WebP, but WebP has broader tool support and faster encoding. Here's the real trade-off, dimension by dimension.

AVIF vs JPEG: Is It Worth Switching From the Old Default?

AVIF files run far smaller than JPEG at the same quality, but JPEG still opens everywhere. Here’s when each format actually wins.

HEIC vs JPEG: Why iPhone Photos Won't Open Everywhere

HEIC halves the file size of an iPhone photo but breaks compatibility everywhere else. Here's why, and when to convert to JPEG instead.

TIFF vs PNG: which lossless format should you use?

TIFF and PNG are both lossless, but they serve different jobs. Compare print/scan workflows against web use, and see when each wins.

PNG vs SVG: raster or vector, and when each one works

PNG and SVG solve different problems: fixed pixels versus scalable shapes. See when SVG can't work at all, and when to rasterize it.

GIF vs MP4: why "GIFs" online are usually video in disguise

GIF and MP4 both play animation, but not the same way. Compare colour limits, file size and autoplay, and see why platforms quietly use MP4.

PDF vs DOCX: Which Should You Send?

PDF locks a document’s layout for reading and printing; DOCX keeps it editable. What each is for, and what survives converting between them.

EPUB vs PDF: Which Is Better for E-books?

EPUB reflows to fit any screen; PDF keeps a fixed, print-faithful page. Which wins depends on the book — here’s how to choose and convert.

EPUB vs MOBI: What’s the Difference for Kindle?

EPUB is the open e-book standard; MOBI is Amazon’s older Kindle format. Amazon has moved away from MOBI, and here’s what that means for you today.

Markdown vs HTML: Which Should You Write In?

Markdown is for writing, HTML is for rendering. How the two relate, why Markdown compiles to HTML, and when to skip Markdown and hand-write HTML instead.

DOCX vs ODT: The Office Default vs the Open Standard

DOCX and ODT are both ISO-standardised, zipped-XML document formats. What actually differs, where each is the default, and which to send when unsure.

CSV vs XLSX: Plain Rows or a Real Workbook?

CSV is universal plain text; XLSX is a typed workbook with formulas and sheets. Compare when each avoids Excel's leading-zero and date-guessing traps.

JSON vs CSV: Nested Data or a Flat Table?

JSON nests data in objects and arrays; CSV is flat rows and columns. Compare streaming, flattening and where JSON Lines fits between them.

JSON vs XML: Why the Web Moved On, and Where XML Still Wins

JSON is terser and native to JavaScript; XML still rules schemas, SOAP and office documents. Compare verbosity, validation and when each format wins.

YAML vs JSON: which should you use for config and data?

YAML and JSON store the same data two different ways. Compare readability, comments and safety, and see which fits config files versus code.

CSV vs TSV: Why the Delimiter Actually Matters

CSV separates columns with commas, TSV with tabs. Why that one character changes quoting rules, Excel behaviour and which format survives messy data.

MP3 vs WAV: compressed delivery vs uncompressed master

WAV stores every sample uncompressed; MP3 throws away what you likely can’t hear to shrink it ~10x. See the real size maths and when each wins.

FLAC vs MP3: lossless compression vs perceptual compression

FLAC keeps every sample and halves file size; MP3 shrinks further by discarding what you likely can’t hear. See the honest trade-off and when each wins.

MP4 vs MOV: What Actually Changes When You Convert

MP4 and MOV are close cousins that often hold the same video. Here is what really differs, why iPhones record MOV, and when converting matters.

MP4 vs WebM: Licensing, Support and File Size

MP4 (H.264) plays almost anywhere; WebM (VP9/AV1) is smaller and royalty-free but less universal off the web. Here is the real trade-off.

MKV vs MP4: The Archivist's Container vs the One That Just Plays

MKV holds anything — every track, subtitle and chapter. MP4 is what plays everywhere. Here's what you gain and lose converting between them.
