CloudConvert
cloudconvert.comCloudConvert is the developer-first choice for file conversion. Its API integrates into business workflows, supports webhooks, custom conversion options, and enterprise SLAs. The web interface is a consumer-friendly layer on top of the same infrastructure.
What it does well
- Professional cloud API with 200+ formats — but charges per conversion after 25 free daily conversions and uploads everything to Amazon S3.
Where it falls short
- -Files uploaded to Amazon S3 — cloud storage during conversion
- -Free tier limited to 25 conversions per day
- -Complex pricing — billed per conversion minute
Pricing: Free ($0) / Pay As You Go (From $6/100 mins) / Packages (From $13/mo)
- 3
Convertio
convertio.coConvertio 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.
What it does well
- Popular cloud-based file converter with 300+ formats — but uploads your files to remote servers and gates batch conversion behind a paid plan.
Where it falls short
- -Files uploaded to remote servers — privacy risk for sensitive images
- -Free tier limited to 25 conversions per day
- -Batch conversion requires paid subscription
Pricing: Free ($0) / Light ($9.99/mo) / Premium ($14.99/mo)
- 4
iLoveIMG
iloveimg.comiLoveIMG positions itself as a complete image editing suite for non-technical users — compression, resizing, cropping, watermarking, and conversion in one place. The UX is polished and beginner-friendly.
What it does well
- Image editing suite with compression, resizing, and conversion — but cloud-based processing and a hard 30-image free tier limit.
Where it falls short
- -Files uploaded to remote servers
- -Free tier limited to 30 images per task
- -Ads on the free tier
Pricing: Free ($0) / Premium ($3.75/mo)
- 5
Zamzar
zamzar.comZamzar built its reputation as the first mainstream online file converter. Its email-delivery model was practical in 2006 when browsers couldn't handle large file processing, but it's now a relic compared to modern browser-native tools.
What it does well
- Established cloud converter founded in 2006 — but sends results by email, limits free conversions to 3 per day, and stores files on remote servers.
Where it falls short
- -Free tier limited to only 3 conversions per day
- -Files uploaded to Zamzar's remote servers
- -Email-delivery workflow adds friction
Pricing: Free ($0) / Basic ($9/mo) / Pro ($20/mo)
- 6
Squoosh
squoosh.appSquoosh is arguably the best single-image compression tool available. Built by Google Chrome Labs, it runs entirely in your browser via WebAssembly, supports AVIF/WebP/MozJPEG encoding, and shows a live side-by-side quality comparison.
What it does well
- File privacy: Local (WASM)
- Google's excellent local image compressor — but handles one image at a time with no batch mode and no ICO, TIFF, or GIF output.
Where it falls short
- -No batch conversion — one image at a time only
- -No ICO, TIFF, BMP, or GIF output formats
- -No HEIC input support
Pricing: Free (open source) ($0)
