About the image and PDF size format checker
Find out why a file may be rejected
The checker compares one image or PDF with the limits you type from the target site. It can check maximum file size, allowed formats, image width and height, aspect ratio, and PDF page count without sending the file to a server.
Start from common file-limit situations
Use custom limits when the site gives exact numbers, or start from common situations such as profile photos, document PDFs, and web images. Requirements for named platforms can change, so always follow the target site.
Clear next steps when a rule fails
Failed image size or format checks point to existing tools such as Image Compressor and image converters when they can help. PDF splitting or compression is shown as text guidance when no matching tool exists yet, so the checker avoids broken links.
FAQ
Common questions and answers about this topic.
Are my files uploaded?
No. The checker reads the file details in your browser and does not send the image or PDF to a server.
Why is there no DPI check?
Browsers do not read embedded DPI consistently across file formats. This tool checks pixel dimensions instead, which are more reliable before upload.
Are the common situations official platform requirements?
No. They are generic starting points. If a target site shows exact limits, type those values into the custom fields.
