A desktop-grade image converter for Windows
Online image converters work for one-off jobs, but they fall apart the moment you have to handle a folder of 500 photos, a 50 MB high-resolution scan, or anything you'd rather not upload to a third-party server. File Converter Pro is the desktop alternative: a Windows 10 / 11 native app that does PNG, JPG, WebP, SVG, BMP, TIFF, GIF, ICO, HEIC and AVIF — all locally, all in one queue.
Behind the simple drag-and-drop UI is a configurable pipeline: quality presets, chroma subsampling, EXIF metadata stripping, dimensional resize, and optional folder-mirroring on output. Photographers use it to push thousands of RAW exports to web JPGs in one go. Designers use it to convert Figma exports to multiple formats in parallel. Devs use it to script icon generation across PNG / WebP / ICO from a single SVG source.
Supported image formats
File Converter Pro supports every commonly used image format on Windows:
- PNG — lossless raster, transparency support, ideal for screenshots and UI assets.
- JPG / JPEG — lossy raster with universal compatibility, the right choice for photos and web delivery.
- WebP — modern web format, 25–35% smaller than JPG at the same quality, lossy or lossless.
- AVIF — next-gen codec from AOM, even smaller than WebP, supported by all current browsers.
- HEIC — Apple's iPhone format. Convert HEIC photos to a Windows-friendly format like JPG or PNG.
- SVG — vector format, scalable to any size; convert to PNG/JPG/WebP for raster delivery.
- BMP / TIFF / GIF — legacy and archival formats. The app handles multi-page TIFF and animated GIF intelligently.
- ICO — Windows icon format with multiple bitmap layers; build icons from PNG sources.
Popular image conversions
PNG to JPG
Shrink screenshots and exports — JPG at quality 85 is 60–90% smaller than the source PNG.
JPG to PNG
Move from lossy JPG to lossless PNG when you need to edit, layer or composite.
HEIC to JPG
Open iPhone HEIC photos on any Windows app — convert in batch with no upload.
WebP to JPG
Restore compatibility with older Office, Photoshop and email clients that don't read WebP.
SVG to PNG
Export vectors to fixed-size PNG bitmaps for slides, social posts and email.
ICO to PNG
Pull individual bitmap layers from Windows .ico files into editable PNGs.
AVIF to JPG
Convert AVIF downloads to JPG when you need universal viewer support.
JPG to WebP
Modernize your image library — WebP is 25–35% smaller than JPG at equal quality.
PNG to WebP
Lossless WebP keeps transparency and beats PNG file size on most images.

Image conversion for real workflows
Photographers use the queue to push edited PNG exports to JPG at quality 90 for client galleries, while keeping the originals untouched. The folder-mirroring option preserves shoot folder structure on the output side.
Designers and marketers generate the multi-format set (PNG + WebP + JPG) from a single source per asset — no more separate exports from Figma, Sketch or Affinity. SVG sources can be rasterized to specific dimensions in a single pass.
iPhone and Android users convert HEIC and HEIF photos to JPG or PNG so they can attach them to Outlook, paste into PowerPoint, or upload to platforms that don't support modern Apple formats.
Web developers bulk-convert legacy JPG and PNG libraries to WebP and AVIF for production deployment. Batch resizing combines with format conversion to produce per-breakpoint asset sets in one run.
FAQ
What image formats does File Converter Pro support?
PNG, JPG/JPEG, WebP, BMP, TIFF, GIF, SVG, ICO, HEIC and AVIF — both as input and output for the formats that round-trip cleanly. The full matrix is shown in the app.
Can I batch convert images on Windows offline?
Yes. The image converter accepts unlimited files in a single queue. Drag a folder of thousands of PNGs or HEICs and they all process locally on Windows 10 or 11 — no upload, no daily cap.
Will image conversion lose quality?
Only when the target format is lossy (JPG, WebP at quality less than 100, AVIF lossy). Lossless conversions like PNG → BMP or PNG → TIFF preserve every pixel. The app shows the projected quality before you run a batch.
How does this compare to web image converters?
Web converters upload your images, watermark some outputs, cap free use at 100 MB or 10 files, and depend on the network. File Converter Pro runs locally on your CPU/GPU with no uploads and no caps, for €6.49 one-time.
