Short, practical write-ups about file formats — what they're for, when to switch, and how to get the best result. No fluff.
WebP vs PNG vs JPG: which image format should you use?
JPG is best for photographs with millions of colours and no transparency. PNG is for graphics, screenshots, and anything that needs a transparent background — it's lossless, so quality never degrades. WebP is Google's modern option that combines both: roughly 25–35% smaller than JPG at similar quality, with optional transparency. The only reason not to use WebP is compatibility — older design tools and some social platforms still prefer PNG or JPG.
Try WebP to PNG →How to compress images without ruining quality
Most photos can be reduced 60–80% in size with no visible quality loss by lowering JPG quality from the camera default (95–100) to around 75–82. PNG screenshots compress best by re-encoding them to WebP or by reducing the colour palette. The Morphix image compressor handles JPG, PNG, and WebP entirely in your browser, so original files never leave your device.
Open compressor →Why iPhone photos open as HEIC and how to fix it
Since iOS 11, iPhones save photos as HEIC (High-Efficiency Image Container). HEIC files are about half the size of JPG at the same quality — great on the phone, awkward everywhere else. Windows, older versions of macOS, most browsers, and many editing tools still don't read HEIC natively. Converting to JPG keeps the image looking the same while making it universally compatible.
Convert HEIC to JPG →Extracting audio from a video (the right way)
If you only need the sound from a video — a podcast recording, a lecture, a music clip — there's no reason to keep the visual track. Stripping it to MP3 or M4A cuts the file size dramatically and lets you play it on any audio player. Morphix uses ffmpeg.wasm to demux the audio stream without re-encoding when possible, preserving the original quality.
Extract MP4 audio →MOV vs MP4: do you really need to convert?
MOV is Apple's QuickTime container, used by iPhone and macOS screen recordings. MP4 is the universal video container based on the same underlying spec (ISO/IEC 14496-14). For the vast majority of MOV files — those that use H.264 or H.265 video — converting to MP4 is a fast container swap, not a re-encode. The video data is identical; only the wrapper changes.
Convert MOV to MP4 →Turning a video clip into a shareable GIF
GIFs are limited to 256 colours per frame and use ancient compression, so a 10-second video can become an enormous GIF. Keep clips short (2–6 seconds), reduce the frame rate to 10–15 fps, and crop to the action. Morphix builds an optimal palette per clip so the resulting GIF stays sharp while remaining sensibly sized.
Make a GIF →Why in-browser conversion matters for privacy
Traditional online converters upload your file to a server. Even when the operator promises to delete it, the file has touched a stranger's machine — logs, backups, and operator access are all possible. WebAssembly changes the game: tools like ffmpeg.wasm let the same conversion code run inside your browser tab, so the file never leaves your device. It's a meaningful upgrade for sensitive content like personal photos, medical recordings, or work-in-progress media.
