Pick the problem you are hitting
The problem you run into, and which ImageToSend tool helps with it. When you are not sure, start with File Preflight to check your file against the measurable requirements first.
The problem
A destination states a maximum file size, and your photo or document exceeds it. Limits vary by destination — check the stated maximum before you prepare the file.
How ImageToSend helps
Run File Preflight with the maximum file size you entered to confirm the mismatch, then use the Smart Resizer to bring the file under that maximum.
The problem
A destination accepts only certain formats (for example JPG but not PNG, or WebP but not HEIC), and your file is in a different format.
How ImageToSend helps
Run File Preflight and enter the accepted format(s) to confirm the mismatch, then use the Image Converter to switch to an accepted format.
The problem
Your photo is rotated sideways, or the subject is poorly framed and needs cropping. A destination may also require a specific orientation or aspect ratio.
How ImageToSend helps
Run File Preflight and enter the required orientation or aspect ratio to confirm the mismatch, then use the Document Editor to rotate, crop, or lock an aspect ratio.
The problem
A destination accepts a single PDF upload, but you have several separate images — for example photos of homework pages, receipts, or document scans.
How ImageToSend helps
Use Images to PDF to combine those images into one multi-page PDF before uploading. Reduce the source images first with the Smart Resizer if the combined file is too large.
The problem
A destination rejected your file but did not make it obvious which requirement was missed — it could be size, format, dimensions, orientation, or aspect ratio.
How ImageToSend helps
Start with File Preflight. Enter every measurable requirement the destination has stated and let it separate what matches from what needs a fix, then open the tool it recommends.
