Frequently Asked Questions
Will converting WMF to PNG lose quality?
It depends on the formats: WMF is uncompressed GDI records (16-bit) and PNG is lossless DEFLATE — screenshots and graphics compress extremely well. Any step from a lossless source into PNG keeps everything; any lossy step re-encodes and discards some data.
Are my files uploaded anywhere during WMF → PNG conversion?
No. This converter runs on WebAssembly inside your browser — your WMF file is read from disk, processed by your device's CPU, and the PNG is written back locally. There is no server upload at any point, which also means no size-based throttling or waiting in queue.
What resolution should I pick when converting WMF to PNG?
PNG is lossless DEFLATE — screenshots and graphics compress extremely well with fixed pixels — choose the output size for where it will be used. Going small saves bytes but can't be undone; going very large wastes space without adding detail beyond the source's quality.
What's the difference between WMF and PNG technically?
WMF is Windows Metafile — the 16-bit ancestor of EMF (Microsoft, 1990 (Windows 3.0)). PNG is Portable Network Graphics — lossless images with full alpha transparency (created 1996 as a patent-free replacement for GIF). In practice, WMF is typically used for legacy Office clip art, old Windows assets, while PNG is the usual choice for screenshots, logos, transparent graphics.
Is PNG still a current format in 2026?
Universal. PNG's "interlaced" option (Adam7) enables progressive loading at 1/64 resolution — obsolete for most uses today, but the option lives on in every save dialog
