Waarom rekenen in de browser telt

Gewone converters sturen privébestanden naar een wachtrij op afstand. De meeste Toolspy-tools draaien in de browser, en zwaardere kunnen WebAssembly op je apparaat gebruiken.

Standaard cloudconverters

Uploadsites
  • Upload verplicht: Het bestand gaat over internet naar de server van iemand anders voordat er iets gebeurt.

  • Bewaarrisico: Geüploade bestanden kunnen in tijdelijke opslag blijven die jij niet beheert.

  • Gedeelde wachtrij: Je wacht op het netwerk en hoe druk die server is.

  • Limieten en prompts: Veel sites zetten daglimieten, accounts of upgradevensters.

Ongeschikt voor vertrouwelijke bestanden, klantenlijsten en financiële documenten.

Toolspy op je apparaat

Draait in de browser
  • Geen upload bij lokale tools: De browser doet het werk. Die tools sturen het bestand niet naar Toolspy.

  • Blijft bij jou: Handig voor facturen, formulieren en privébestanden die het apparaat niet mogen verlaten.

  • Geen gedeelde rij: Er is geen uploadwachtrij. De snelheid hangt van je apparaat af.

  • Geen account: Open de tool en gebruik hem. De gratis lokale tools vragen geen abonnement.

Lokale tools houden het bestand op je apparaat. Een pagina die iets op het openbare web moet opzoeken, zegt dat.

Privéverwerking

Wat er met je bestand gebeurt

  1. 1. Jouw apparaat

    Het bestand opent in de browser. Het wordt niet naar Toolspy gestuurd.

  2. 2. Browser-engine

    De tool draait in je browser en je bestand blijft op je apparaat.

  3. 3. Direct resultaat

    Het resultaat wordt meteen op je apparaat opgeslagen.

Waarom dit telt

Zodat het bestand niet weg hoeft

Beeld-, PDF- en datatools zijn voor kort lokaal werk. Een paar publieke lookups (zoals een profiel-URL) gebruiken wel een server — die pagina zegt dat.

  • Geen accountmuur

    Open een tool en gebruik hem. Geen aanmelding vóór het resultaat.

  • Zelfde op telefoon en desktop

    Als de browser de pagina kan, installeer je geen app.

  • Duidelijke grenzen

    Elke toolpagina zegt wat hij aanvaardt. Rekenmachines zijn schattingen, geen officiële uitkomsten.

Why people use Toolspy

A few honest reasons the tools are worth keeping in your bookmarks.

Your files stay on your device

Most tools run entirely in your browser, so images and documents are processed locally instead of being uploaded to a server.

No account, no paywall

Every tool is free to open and use. There's nothing to sign up for and no feature locked behind a subscription.

Built to be quick

Since the work happens on your machine, there's no waiting on uploads or queues - most tasks finish in a few seconds.

One place for everyday tasks

Compress an image, merge a PDF, format JSON, or run a quick calculation without hunting for a different site each time.

Works on phone and desktop

The tools are responsive, so the same features work in a mobile browser as they do on a laptop - nothing to install.

Clear about what each tool does

Every tool page explains how it works, which formats it supports, and what its limits are, so there are no surprises.

Notes on privacy and content quality

Clear expectations, less surprise.

Privacy-first by design

Many tools run locally in your browser. If a tool needs server-side processing, treat your files as temporary and avoid uploading anything sensitive.

Simple, not salesy

We focus on clear inputs, predictable outputs, and practical guidance so the tool is easy to use even if you’re in a hurry.

Built for real workflows

Batch-friendly where it matters, sensible defaults, and links to related tools so you can finish the entire task in one place.

Common pitfalls

Know what the tool expects

Some tools need a URL, some need a file, and some need average metrics. Read the labels and use realistic inputs.

Use the right tool for the goal

For example: optimize images for web delivery, but keep high-quality originals for design work.

Treat estimates as estimates

Finance and engagement calculators are for planning and comparisons - not official results.

Frequently asked questions

Quick answers about how the site works.

Are all Toolspy tools really free to use?

Yes. The tools are free to use and don’t require creating an account. If we introduce limits or paid features in the future, we’ll make that clear on the relevant pages.

How do you keep my files secure when using Toolspy tools?

Many tools run locally in your browser, so inputs are processed on your device. Some tools may require server-side processing depending on the feature. Always avoid uploading sensitive files unless you trust the workflow for that tool.

What file formats and sizes can I work with on Toolspy?

Formats and size limits vary by tool. Image tools typically support common formats like JPG, PNG, WebP and more. PDF tools support common PDF workflows (merge, split, compress, convert). Check each tool page for the exact limits and supported formats.

Do I need to download or install anything to use Toolspy?

No. Toolspy tools are browser-based. Open a tool page, provide the input, and get the result.

Can I use Toolspy tools on my phone or tablet?

Yes. The site is designed to work on mobile, tablet, and desktop. Some workflows are easier on a larger screen, but the tools are usable on phones too.

How does batch processing work, and how many files can I process?

Batch support depends on the tool. Some tools let you process multiple files in one run, while others focus on a single input. Check the tool page for what’s supported.

What makes Toolspy better than other free online tool websites?

Toolspy focuses on a simple workflow: clear inputs, predictable outputs, and short guides for common pitfalls. Many tools run in-browser and don’t require signup.

Are these tools good enough for business and professional use?

They can be. Many users rely on these tools for everyday work tasks. For compliance-heavy or sensitive workflows, validate the output and use the right tool for your specific requirements.

How often do you add new tools or update existing ones?

Tools are updated over time as we improve quality and add new features. If you have a request, you can share it on the feedback page.

Can I use Toolspy tools for my business or client work?
