What every file extension actually is, how to open it, and how to convert it on iPhone, iPad or Mac — entirely on-device.
The AV1-based successor to WebP — smaller files than either JPEG or WebP, but the newest format your phone or browser is likely to encounter.
Windows' original uncompressed image format — simple, huge, and still generated by some legacy software and screenshot tools.
Adobe's open camera-RAW format — the one RAW variant that isn't tied to a single camera brand.
The 1987 format that refuses to die — capped at 256 colors, but still the universal way to share a short, looping animation.
Apple's default photo format since iOS 11 — half the size of JPEG at the same quality.
The Windows icon and favicon container — the one image format built to hold several sizes of the same picture at once.
The wavelet-based JPEG successor that never went mainstream — still the standard in medical imaging, digital cinema, and satellite photography.
The royalty-free successor to JPEG — smaller files, lossless recompression of old JPEGs, and support that's still catching up across apps.
The lossless, transparency-friendly format that never throws away a pixel — and the one Filemorph's background removal always outputs.
Uncompressed camera-sensor data — CR2, NEF, ARW, and other vendor extensions that hold everything a JPEG throws away.
The one common image format that isn't made of pixels — text-based drawing instructions that stay sharp at any size.
The uncompressed (or losslessly compressed) format professional printing, scanning, and archiving still standardize on.
Google's web image format — smaller than JPEG or PNG, but plenty of older software still can't open it.
The plain-text spreadsheet format every data tool can read — and the common language Filemorph uses to move data between JSON, Excel, and PDF.
The Word document format that's actually a ZIP file underneath — and one of the few formats Filemorph both reads and writes.
The open ebook standard nearly every e-reader supports — except the one made by the company that sells the most ebooks.
The data format behind nearly every app and API — readable by people, and the one thing Filemorph can turn straight into a spreadsheet.
The older Kindle ebook format Amazon has since moved past — Filemorph reads it in one direction, into EPUB.
Plain text with lightweight formatting marks — and the one text format Filemorph can pull straight out of a PDF, a DOCX, or an Excel sheet.
The transaction-data format banks hand off to accounting software — imported by Quicken, GnuCash, and Xero, never opened like a normal document.
The one document format built to look identical everywhere — and the format Filemorph can merge, split, compress, sign, and pull data out of, all on-device.
Microsoft's 1987 plain-text-plus-formatting format — still the one nearly every word processor and text editor can open without a plugin.
Excel's modern spreadsheet format — and, on iOS 26, one of the few things Filemorph can build directly out of a PDF's tables.
The codec inside almost every modern Apple audio file — M4A's engine, not a separate format of its own.
Apple's original uncompressed audio format — WAV's older cousin, still the default in GarageBand and Logic Pro.
Compressed audio that loses nothing — and, on iPhone, a format Filemorph can read and edit but can't create.
Apple's everyday audio container — and the format almost every audio edit in Filemorph saves to, no matter what file you started with.
Apple's ringtone container — the same AAC audio as M4A, capped at 40 seconds so iOS recognizes it as a ringtone instead of a song.
The format that made digital music universal — and the one audio format Filemorph can open everywhere but can't create new copies of.
Uncompressed PCM audio — the professional and archival standard, and the format nearly every compressed audio file decodes down to before editing.
Apple's iTunes-store video container — nearly identical to MP4, except when FairPlay DRM locks it to your Apple ID.
Apple's native video container — the format an iPhone actually records to before anything gets shared as MP4.
The universal video container — the format almost everything expects, and the one Filemorph produces most video tools' output as.
