TinyTool vs Convertio
Convertio is a popular cloud-based file converter that supports over 300 formats including documents, images, audio, video, and ebooks — but processes every file on its servers.
File conversion is one of the most common tasks people search for online — converting a PNG to JPG, a PDF page to an image, or a stack of images into a PDF. The question is whether the tool you use handles your files securely and without friction.
Convertio is one of the most widely recognised file conversion services on the web. It supports over 300 formats spanning images, documents, audio, video, ebooks, and presentations. Upload a file, choose an output format, and Convertio's servers handle the rest. It is a versatile catch-all converter that covers use cases no browser-based tool can match — particularly audio, video, and document-to-document conversions.
TinyTool focuses on the formats people actually need every day — image conversion (JPEG, PNG, WebP, AVIF), PDF-to-image, image-to-PDF, and data format conversion (JSON, YAML, CSV) — and handles all of them entirely in your browser. No upload, no server round-trip, no waiting. Your files never leave your device, there are no daily quotas, and results are instant regardless of your internet speed.

The verdict
TinyTool is the better choice for fast, private image and PDF conversions with no upload wait, no limits, and no sign-up.

For everyday image and PDF conversion, TinyTool delivers the same results instantly and without ever touching your files.
Frequently asked questions
Is Convertio really free?
Convertio's web interface is free for basic use but caps file sizes and limits daily conversions on the free tier. Larger files or higher volumes require a paid subscription. TinyTool is completely free with no daily limits and no file size caps imposed by the tool itself.
Does Convertio upload my files to a server?
Yes. Convertio is a cloud-based service — every file you convert is uploaded to its servers, processed, and then made available for download. Files are deleted after a set period. TinyTool converts images and PDFs entirely in your browser, so your files are never uploaded anywhere.
Can TinyTool convert the same formats as Convertio?
Not all of them. Convertio supports over 300 formats including audio, video, ebooks, and office documents — use cases that require server-side libraries. TinyTool covers the most common everyday needs: image formats (JPEG, PNG, WebP, AVIF), PDF conversions, and data formats (JSON, YAML, CSV). For audio, video, or DOCX conversion, Convertio is the right tool.
Which is faster for converting images?
TinyTool is significantly faster for images because it converts in the browser using the Canvas API — there is no upload or download step. A 5 MB image that might take 10–30 seconds to upload, convert, and download on Convertio is done in under a second on TinyTool.
