Platform Overview

Two different approaches

We respect what Convertio does well. Here's how each tool works.

Convertio: Popular cloud-based file converter with 300+ formats — but uploads your files to remote servers and gates batch conversion behind a paid plan.

Convertio is one of the most recognized file conversion brands online, built around a simple paste-or-upload interface that handles 300+ format combinations. Its breadth is its main selling point — documents, audio, video, and images all in one place.

The trade-off: all processing happens on Convertio's remote servers. Files are uploaded, converted, and stored temporarily in the cloud. The free tier is limited to 100 MB per file and 25 conversions per day, and batch conversion requires a paid subscription.

Why Switch

Why choose Trndinn over Convertio

Trndinn converts images entirely in your browser using the Canvas API — zero uploads, zero server round-trips, unlimited batch processing, and instant results.

Zero uploads — images never leave your device

Convertio uploads every file to their servers. Trndinn's converter runs entirely in your browser via the Canvas API. Your images are processed locally and never transmitted anywhere.

Unlimited conversions — no daily cap

Convertio's free tier allows 25 conversions per day. Trndinn has no daily limit, no file count cap, and no subscription required to convert as many images as you need.

Instant processing — no upload/download round-trip

Cloud converters add latency for upload, server processing, and download. Trndinn converts locally in milliseconds — a 10 MB PNG to JPG completes before Convertio finishes uploading.

33 image formats — purpose-built for images

Trndinn focuses on the 33 most common image conversion pairs with a tool dedicated to each one. Convertio's generalist approach means image tools aren't optimized for quality or speed.
