About Image Conversion Tools
The right file format depends on what you're doing with the image. JPG is small and universal but lossy — perfect for photos on the web. PNG keeps every pixel and supports transparency, ideal for logos and screenshots. WebP and AVIF are modern formats that compress 25–50% smaller than JPG with the same quality, but older browsers and design apps still don't read them. HEIC is what your iPhone shoots in by default; nothing outside the Apple ecosystem opens it cleanly.
This collection covers every direction you need: convert between any of the seven major formats, batch-convert a folder of HEIC photos to JPG before sharing, turn a multi-page PDF back into individual images, or stitch a stack of images into a single PDF. Every converter runs in your browser, doesn't store the file, and produces an output you can download immediately.
When to use which: JPG for photos & web hero images; PNG for logos, icons, screenshots, anything with transparency; WebP if all your viewers are on modern browsers and you want smaller files; AVIF if you want the absolute smallest size and don't care about Safari < 16; PDF for printable, email-attachable, archival assets.
Why use a browser-based tool?
Every tool in this category runs entirely in your browser — your image never leaves your device unencrypted, you do not have to install a desktop app, and the same workflow works on Windows, macOS, Linux, iPad and Android. Most operations finish in under two seconds because they run on a CDN-edge worker close to you. AI-powered tools take a few seconds longer (the model inference dominates the wall time).
When to upgrade to Premium
Upgrade once you find yourself running the same tool more than a handful of times a week. Premium lifts the daily quota cap, unlocks bulk mode (drop 200 files at once instead of one), and queues your jobs ahead of free users. It also unlocks the full HD / 4K / 8K download tier on every wallpaper detail page, removes site ads, and gives you a Premium badge if you also post as a Creator.
How these tools compare to desktop software
For one-off jobs and modest workflows, browser tools save you the cost and friction of buying a desktop license. Photoshop, Lightroom, Affinity and the rest of the desktop suite are still the right call for complex, multi-step editing — colour-graded photo retouches, multi-layer composites, large-batch RAW conversion. Our tools are tuned for everything in between: the daily mix of resize, crop, convert, compress, watermark, and 'remove the background of this one product photo'.
