AltFTool vs CloudConvert

CloudConvert covers 212 formats, including CAD, ebook, archive and font types that a browser has no decoder for. That breadth is the product and it is not something we approach. What a browser can do is the short head of the distribution: HEIC to JPG, WebP to PNG, images to PDF, PDF to images, CSV to JSON. Those are the conversions that burn CloudConvert's ten free credits a day, and they need no server at all. For anything outside that list, their credits are cheap and the isolated-container architecture is well engineered.

CloudConvert's free tier, in their own words

• Free plan gives 10 conversion credits per day, with a daily reset (cloudconvert.com/pricing, checked 2026-07-25)
• Free plan caps file size at 1 GB and processing time at 5 minutes per conversion
• Free plan allows 5 concurrent tasks and runs at 'Low' processing priority; paid tiers are 'High'
• Credits are consumed per conversion: 1 base credit for a general conversion, 2 for Office-to-PDF, 4 for PDF-to-Office, plus 1 more credit for every extra minute of conversion time
• A free account is required; the pricing page states 'Start free with 10 conversions per day. No credit card required.'
• Free plan excludes dedicated capacity, custom fonts, SLA, DPA, SSO/SAML and team billing

Paid pricing: Package US$18 one-time for 1,000 credits (US$0.018/credit); Subscription US$10/month for 1,000 credits/month (US$0.01/credit)

What CloudConvert does better

Plenty of people should keep paying for CloudConvert, and these are the reasons why.

• Genuinely broad and deep format coverage - the site states it handles 212 formats across 11 categories, including CAD, ebook, archive and font types that no in-browser toolbox can decode.
• Real conversion controls and a first-class API: per-conversion codec, bitrate, resolution and quality settings, plus a documented jobs API (import / convert / export tasks) that plugs into your own storage and application logic.
• Serious operational engineering for large or sensitive jobs: unlimited file size and processing time on paid plans, each conversion runs in a separate isolated container, you choose the geographic processing region, and files are 'kept only for processing and deleted immediately afterwards' with SSL in transit, a DPA, 99.9% SLA and SSO available.

And what AltFTool does not do

• 212 formats versus a couple of dozen. No CAD, no ebook formats, no archives, no fonts — a browser cannot decode them.
• No conversion controls. CloudConvert lets you set codec, bitrate, resolution and quality per job; our converters use sensible defaults.
• No API, no SLA, no DPA, no regional processing choice, no isolated containers — none of the operational guarantees a business conversion pipeline needs.

Questions people actually ask

Does AltFTool convert as many formats as CloudConvert?

Nowhere near. They list 212 formats across 11 categories. We cover the common image, document and data conversions a browser can decode natively, which is a much shorter list.

Do I need an account?

No. CloudConvert requires a free account for its 10 daily credits; our converters open and run without signing in.

What about a 1 GB video conversion?

Use CloudConvert. Their free plan already accepts 1 GB files with a 5-minute processing budget, and paid plans remove both limits. A browser tab is the wrong place for that job.
