How it works

For images, enter the maximum file size, accepted format, dimensions, or aspect ratio. Uploadable diagnoses the original, explains the planned changes, and validates the generated file again before download.

What “ready” means

For an available tool, Ready to upload means the generated file matches the technical rules you entered and that Uploadable can verify. A third-party website may still apply additional unpublished rules.

Frequently asked questions

What file types can I use today?

Uploadable supports JPG, PNG, WebP, and PDF. Images and PDFs use separate local processors with format-specific checks and safety limits.

Does Uploadable send my file to a server?

No. Currently supported images are inspected, transformed, and validated in your browser. The source and generated image are not sent to Uploadable servers.

Does Ready to upload guarantee acceptance?

No. It confirms the technical rules you entered and the app could verify. The destination website may have other requirements.
