1. Read the exact file requirements
Find the allowed file type (often JPG), pixel width and height, and maximum KB. These are three separate conditions. If your form requires 300 × 300 px and no more than 50 KB, changing the file extension alone will not help.
2. Check whether your dimensions are correct
Pixel dimensions describe the number of pixels across and down. A 1200 × 800 image is not 300 × 300. A square crop is one method to create exact square dimensions without stretching a face; a fit-with-padding option can preserve the entire photo when cropping is unacceptable.
3. Convert to the required file format
JPG, PNG and WebP have different encoding and transparency behavior. Renaming a file extension is not equivalent to converting the file. If your form requires JPG, generate and download an actual JPG file.
4. Reduce file size while preserving required pixels
Quality adjustment can reduce JPEG and WebP file sizes; the possible reduction depends on detail and dimensions. If the form demands exact dimensions, automatically resizing smaller could cause rejection. Some targets are not achievable without losing too much information.
5. Validate the result before submitting
Use PixReqly Upload Requirements Fixer to enter your exact requirements, prepare an image and check output format, dimensions and file size. This does not guarantee acceptance because the form may also require specific background, head position or other properties.
Common questions
Is a 50 KB photo always possible?
No. At certain dimensions and for complex images, JPEG or WebP might remain larger than the target. Consider another accepted image type, a more suitable source image, or follow the specific platform's instructions.
Do you store my picture?
No, the image processing happens in the browser and is not uploaded to a conversion server. Normal requests to host the website are separate.

File too large
Find the maximum size allowed by the portal, such as 50KB or 200KB. Compress the image to slightly below that number. If the form also specifies exact dimensions, do not reduce dimensions as a side effect of compression. JPG and WebP usually offer greater size reduction for photographs than PNG, but only use a format the form explicitly accepts.
Invalid dimensions or aspect ratio
Compare the required width and height to the downloaded image's actual pixel dimensions. A common mistake is entering width 300 while aspect ratio lock is on, expecting the height to also become 300. To make an exact square, unlock aspect ratio and choose crop to exact size. Avoid stretching a portrait unless the destination explicitly permits it.
Unsupported image type and corrupted extension
A website may reject WebP despite accepting JPG or PNG. Convert the file using the Image Format Converter; renaming a .webp file to .jpg does not rewrite its image encoding. Download the converted file and re-upload the new copy. Also check if the form requires a particular filename style or restricts special characters.
When all checks pass but the form still fails
Some forms check more than size, pixels and file encoding: background color, face framing, color profile, filename, or server-side limits. Try a mainstream JPG, a simple filename, and another browser, then consult the portal's support documentation. The Upload Requirements Fixer validates the constraints you enter; it cannot promise acceptance by every third-party website.
