Supports 15+ formats including JPG, PNG, WebP, GIF, BMP, TIFF, SVG, ICO, AVIF, HEIC
A free image converter is a browser-based tool that lets you change an image’s file format such as JPG to PNG or HEIC to JPG without installing software or uploading files to a server. Image Converter Pro on GD Graphic supports 15+ formats, processes everything locally for full privacy, and adds batch conversion, compression, and PDF creation in one free tool.
If you’ve ever hit a wall trying to open an iPhone photo on a Windows PC, upload a PNG where only JPG is accepted, or shrink a bloated image for a faster website, the problem is always the same: the wrong format for the job. A free image converter solves that instantly, and understanding which format to use — and when — saves you time on every project going forward.

Every image format is a trade-off between file size, quality, and compatibility. Using the wrong one silently costs you:
Picking the right format isn’t a technical afterthought — it’s part of doing the job properly, whether you’re a designer, developer, or just organizing your own photo library.
Image Converter Pro is GD Graphic’s free, browser-based image conversion tool. Unlike most “free” converters that quietly upload your files to a remote server, it runs the entire conversion process locally on your device using your browser’s own processing power.
Key capabilities at a glance:
| Feature | Details |

| Compression presets | Small, Balanced, High Quality |
| PDF creation | Combine multiple images into one sorted PDF |
| File size limit | Up to 200MB per batch |
| Cost | Free, no account required |
Regardless of which formats you’re converting between, the workflow is the same:
No installation, no watermark, and no waiting on a server queue.
Converting JPG to PNG is the right move whenever transparency matters — logos, product cutouts, icons, or any graphic that needs to sit cleanly over another background. JPG doesn’t support transparency and uses lossy compression, so re-exporting a logo as PNG preserves sharp edges and a clean, see-through background.
Use JPG to PNG when:
PNG to WebP conversion is one of the highest-impact changes you can make for website performance. WebP typically cuts file size by 25–80% compared to PNG or JPG while keeping visual quality nearly identical, which directly improves Largest Contentful Paint (LCP) — a core Google ranking signal.
| Format | Typical File Size | Transparency | Best Use |
|---|---|---|---|
| PNG | Large | Yes | Logos, graphics needing transparency |
| JPG | Medium | No | Photos, general web images |
| WebP | Small | Yes | Modern websites, fast-loading pages |
| AVIF | Smallest | Yes | Cutting-edge sites prioritizing Core Web Vitals |
For an even leaner site footprint, pair converted images with GD Graphic’s Favicon Generator so your entire visual identity — from hero images to the browser tab icon — stays optimized.
Apple’s HEIC format compresses beautifully, but it isn’t universally supported. Many Windows apps, older devices, and some websites simply won’t open it. Converting HEIC to JPG takes seconds and guarantees the photo opens anywhere — no quality loss, no compatibility guesswork.
Common reasons to convert HEIC to JPG:
Manually converting one file at a time is fine for a single photo — but not for a client project, a product catalog, or an old photo library. Image Converter Pro’s batch mode processes up to 50 files simultaneously, applying the same output format and compression settings across the entire set. This is the difference between a five-minute task and a two-hour one.
Beyond format conversion, Image Converter Pro can combine several images into a single, ordered PDF — useful for portfolios, invoices, scanned documents, or presentations. Enable “Combine All into Single PDF” and “Sort by Filename” before converting to keep pages in the correct order automatically.
Photographers working with camera RAW files know they’re too large and unwieldy for web or client delivery straight out of the camera. Image Converter Pro converts RAW files into JPEG or TIFF, giving you a fast path from “camera card” to “client-ready gallery” without opening dedicated editing software.
Many free online converters route your files through a remote server — which means your images, even sensitive ones, briefly exist on someone else’s infrastructure. Because Image Converter Pro processes files entirely in your browser, nothing is ever uploaded. This matters most when converting:
| Your Goal | Best Format |
|---|---|
| Fastest-loading web images | WebP or AVIF |
| Logos/icons with transparency | PNG |
| General photography | JPG |
| Universal compatibility | JPG or PDF |
| Print-quality archiving | TIFF |
| Browser tab icon | ICO |
Yes. Image Converter Pro is 100% free with no sign-up, subscription, or hidden watermark. All formats, batch conversion, and PDF features are included at no cost.
No. All conversion happens locally inside your browser, so your files never leave your device — a meaningful privacy advantage over most online converters.
WebP or AVIF, since both offer significantly smaller file sizes than JPG or PNG with minimal visible quality loss, which improves page load speed and Core Web Vitals scores.
Yes. The batch converter processes up to 50 files at once with the same format and quality settings applied across all of them, saving significant time on larger projects.
