Free online file tools — no upload required

Zoffle is a collection of everyday file utilities that run entirely inside your web browser. Unlike most online converters, your files are never uploaded to a server — all processing happens locally on your own device using modern browser technology. That means no waiting for uploads, no privacy concerns, and no account required.

Compress and convert images

Reduce the file size of JPG, PNG and WebP images, or convert between these formats. Adjust the quality level and set a maximum width to resize images for websites, email attachments or online forms. Process multiple images at once and download them as a ZIP archive.

Merge, split, rotate PDF files and convert images to PDF

Combine several PDF documents into a single file in any order you choose, or split one PDF into separate files — either one file per page or by custom page ranges such as 1-3, 5, 7-8. Useful for combining scanned documents, invoices or contract appendices.

Convert CSV, Excel and JSON

Move tabular data between CSV, Excel (XLSX) and JSON formats. Convert a spreadsheet export into JSON for a developer, turn a CSV file into a proper Excel workbook, or flatten JSON data into a spreadsheet you can open anywhere.

Frequently asked questions

Are my files uploaded to a server?

No. Every conversion runs in your browser using JavaScript. Your files never leave your device, which is why the tools work instantly even with large files.

Do I need to create an account?

No account is needed for the free tier. A Pro subscription only requires an email address, which is used to verify your subscription.

What is included in the free version?

Three conversions per day across all tools, with a 10 MB limit per file. The counter resets automatically each day.

What does Pro cost and can I cancel?

Pro costs €10 + VAT per month and removes all limits and ads. You can cancel at any time from the "Manage subscription" button — there is no minimum term.

Which browsers are supported?

Zoffle works in all modern browsers including Chrome, Safari, Firefox and Edge, on both desktop and mobile.
