PEREFILE is a Russian online file-conversion service that helps individuals and businesses work with documents, images, video, audio, web pages and archives directly in a browser, without installing software. Users can convert files between formats, merge or split documents, compress and resize files, extract audio from video, and save web pages as PDFs. Supported examples include PDF and Word, HEIC and JPG, MP4 and AVI, and ZIP and RAR. The service also offers ready-made presets for tasks such as preparing images for marketplaces, social media, printing and the web, including presets for Wildberries and Ozon.

To use PEREFILE, customers upload files, choose a format or preset, adjust available settings, then track processing and download results individually or as an archive. Batch processing is available, subject to plan limits. PEREFILE offers a free plan as well as paid subscriptions, with transparent pricing and the option to cancel at any time. Files are transferred over HTTPS, processed on servers in Russia and automatically deleted according to the selected plan’s storage period.
