Frequently Asked Questions

Yes. All 37 studios open immediately with no account, no credit card, no daily task quota and no watermark on exported files. The site is funded by advertising, not by charging for processing.

For the local-first studios, no: compression, PDF merging, JSON formatting, hashing, coordinate conversion and similar work run inside your browser tab with Canvas, Web Audio, SubtleCrypto, Web Workers, pdf-lib and pdf.js. Your input never reaches our servers.

A few network studios are request-based by design — HTTP and API checks, DNS record lookups, SSL certificate inspection and website status checks. Those necessarily contact the host you ask about, and their panels say so. Never point them at credentials you care about.

Local studios keep the bytes in your tab, which is stronger than uploading to a hosted converter. Still check each studio's privacy panel, remember that browser extensions installed on your machine can read the page, and avoid pasting secrets into any network-dependent studio.

Decoding, rasterising and archiving happen in your device's RAM instead of on a remote render farm, so the ceiling is set by your hardware and browser tab limits. Desktop browsers handle substantially larger PDFs, audio waveforms and ZIP archives than mobile tabs.

Yes for the local studios. Once a studio's JavaScript has loaded, purely local operations keep running with the network offline, and the site can be installed as a progressive web app for offline access.

Current Chrome, Edge, Firefox, Safari and Brave on desktop and mobile. Studios that rely on WebAssembly, Web Workers, Web Audio or the File System Access API need those features enabled; if a studio cannot run, it tells you which capability is missing.

The image, PDF and data studios support batch input with per-file settings, so you can compress, convert, merge or validate many files in one pass. Queue depth is limited by available memory — split very large batches into groups.

SVG for icons, logos and diagrams that must stay sharp at any size; WebP at quality 75–82 for web photography and UI screenshots; PNG when you need lossless transparency; JPEG when maximum compatibility with legacy email clients or print pipelines matters.

Lossy formats trade bytes for artefacts, so the answer depends on the setting. The image studio shows the resulting file size alongside a visual preview and a PSNR diff, so you can see what you are giving up before you export rather than discovering it later.

Yes. Code snippets, formatted data, QR and barcode exports, and transformed media produced from your own inputs carry no platform restrictions and require no attribution. Licences for third-party fonts, icons or source assets remain yours to verify.

Round-tripping is lossless for text-based data such as JSON, YAML, XML, CSV and SQL. It is not lossless between lossy media formats: converting JPEG to WebP and back will not restore the original pixels, so always keep a master copy.

Local studios implement published algorithms rather than approximations: SHA-2 and SHA-3 for digests, WCAG 2.x and APCA for contrast, SI definitions for unit conversion, standard geodesy formulae for bearing and distance. No result is sent anywhere to be computed.

Each studio ships with known-input checks, and results that matter — checksums, diffs, conversions — are verifiable by you on the spot with a second tool. Anything we cannot verify locally is labelled as best-effort inside the studio.

Core algorithms are deterministic and identical everywhere. Presentation can differ slightly: number and date formatting follow your browser's locale, and text or font metrics vary with installed fonts and rendering engines.

Send the tool name, your browser and version, and a minimal input that reproduces it to contact@thefreeaitools.com. Do not attach real credentials or confidential documents — a stripped-down sample is almost always enough for us to reproduce the bug.

Yes. The embedded-tools library provides embedding snippets for the browser-only studios, so you can drop a compressor, formatter or converter into your own page. Everything still runs client-side on your visitors' devices.

Use the contact page and describe the task rather than the tool — what you are trying to produce, from what input, and what the current workaround costs you. Requests that name a concrete workflow are the ones we can act on.

Email security@thefreeaitools.com with a description and reproduction steps. Please do not attach live credentials, tokens or private documents in the first message — we will arrange a safe channel if one is needed.
