> All Free Image Tools
Every tool on tooldev.app is free, requires no account, and processes your files entirely in the browser. Nothing is uploaded to any server — all conversions happen locally using the Canvas API. Below is the current set of supported tools and guides.
> Format Converters
The main hub: convert between PNG, JPG, WebP, AVIF, GIF, BMP, and ICO in one place. Supports batch upload and ZIP download. All seven format pairs in a single tool.
Reduce lossless PNG files by 25–50% using WebP's dictionary-based compression. Transparency is preserved. Ideal for web delivery where PNG is the source of truth.
Re-encode JPEG photos to WebP for smaller file sizes with comparable visual quality. Choose lossy WebP for photos or lossless for screenshots with JPEG artifacts that need cleaning.
Convert WebP images to lossless PNG for editing workflows, older email clients, or any environment that does not yet support WebP. Transparency round-trips cleanly.
Export WebP to JPEG for maximum compatibility — useful for sharing on platforms and apps that still expect JPEG. Transparent areas are flattened to a solid background.
Convert photos incorrectly stored as PNG to JPEG for smaller file sizes. Transparency is flattened to white (or a custom background). Not recommended for logos or graphics with hard edges.
Make a lossless canonical copy of a JPEG before editing or compositing. Note that PNG cannot recover detail lost during the original JPEG compression.
Convert iPhone HEIC photos to universally compatible JPG in your browser via libheif WebAssembly. A compatibility tool — JPG output is larger than HEIC.
Rasterize vector SVG to PNG (or JPG) at 1×, 2×, 4× or a custom width, with transparency preserved. Renders on an HTML5 Canvas — nothing is uploaded.
> Comparison Guides
When does WebP actually beat PNG, and when does lossless PNG win? Covers compression ratios, transparency handling, browser support, and editing-workflow trade-offs.
Side-by-side comparison of the two leading next-gen formats: encoding speed, file size at equal quality, HDR support, and current browser compatibility data.
> Privacy & Utility
Strip GPS location, camera model, timestamps and all hidden EXIF data from JPEG photos. Everything runs in your browser — files are never uploaded. Batch + ZIP.
Resize photos to exact pixels or one-click social media presets (Instagram, YouTube, Twitter, Facebook). Step-down scaling for sharp output — all in your browser, no upload.
Resize any image to YouTube's 1280×720 or 1920×1080 HD thumbnail spec, kept well under the 2MB limit. Includes a 2026 safe-zone guide — all in your browser, no upload.
AI background removal that runs entirely in your browser via WebAssembly — get a transparent PNG back, no upload, no account. Works on portraits, products, and logos.
