How to finish your task

60 useful tasks with source previews and downloadable results. Files stay on your device. Add files and review settings. Create the result, check the preview, actual size and limitations, then download a new file.

實際例子

For a photo upload with a 300 KB limit, enter 300 and check the actual bytes and pixel dimensions before saving.

範圍和限制

Allow resizing if the chosen minimum quality cannot meet the limit. JPEG turns transparent areas white.

Files are not uploaded to a server. Outputs are new files, so originals remain unchanged. Review the result before saving.

Signatures and business documents

Place a signature or create a quotation or invoice, then review the actual PDF.
