Fix “file size exceeds the maximum limit”
“File size exceeds the maximum limit” means your image is larger than the form permits. The fix is to compress it to at or below that limit before uploading again.
Portals use similar wording: “photo too large to upload”, “photo size too big to upload”, “file exceeds maximum size”, or “maximum file size is X KB”. Note whether the limit is in KB or MB.
Find the limit beside the upload field — often “max 50 KB” or “maximum 200 KB”. Type that KB value in the editable Max file size field below (sample default is 100 KB). If you only see the error after uploading, check the portal’s help page; do not guess a limit. If the error mentions pixels instead, see our page for input image exceeds pixel limit.
Requirement summary
- Maximum file size
- 100 KB
- Accepted format
- JPG
- Examples only
- 50 KB (photos), 20 KB (signatures), 200 KB (scans) — your form’s stated limit always wins
Fix it now
Requirement fields below are editable. Change them to match your form, then drop your file in to check and download a version that fits.
1. Enter the form's requirements
Copy these from the upload instructions on your form. Leave a field blank if the form does not specify it. Or paste the portal text below — we only fill high-confidence fields and flag anything ambiguous.
We can open JPG, PNG and WebP. Pick the format(s) your form accepts and we output one of them. iPhone HEIC is converted where your browser can decode it — if it cannot, export as JPG on the device first.
2. Select your photo or signature

JPG, PNG, WebP, HEIC (Safari/iOS only) — or paste / take a photo

Step by step
Find the limit
Read the error message or upload instructions for the maximum size, usually in KB or MB.
Type your form’s KB limit in the fields above
Change Max file size to your portal’s cap (for example 50 or 200). The sample default is 100 KB — replace it with your form’s number.
Fix and download
Drop your photo in, download the compressed file, and upload it again.
Frequently asked questions
- What does "file size exceeds the maximum limit" mean?
- The portal rejected your upload because the image file is larger than its KB or MB cap. Compress the photo to at or below the stated limit, then upload the smaller file.
- How do I fix a photo too large to upload?
- Read the maximum file size on the form, type that KB limit in the Max file size field below, drop your photo in, and download a compressed version that fits. The file never leaves your browser.
- What if I see "photo size too big to upload" or "file exceeds maximum size"?
- Those are the same type of error — the file is over the size cap. Enter your form’s limit in KB in the editable fields below, fix the file, and try uploading again.
- My form says "file size exceeded! maximum allowed size is 20 KB" — is 20 KB even possible?
- Yes, though it is tight for a photograph. 20 KB is a limit usually set for signatures and small headshots. Type 20 into Max file size below. If the result looks too soft, crop closer so fewer pixels share the budget, and reduce the pixel dimensions as well — a 1500 px wide photo squeezed into 20 KB will always look worse than a 600 px one at the same size.
- What about "your file exceeds the 1MB limit"?
- Same fix, different unit. 1 MB is either 1,000 KB or 1,024 KB depending on who wrote the form, and the safest move is to aim below both — enter about 950 KB. Sitting exactly on a boundary is how a file that looks compliant gets rejected anyway.
- Is "maximum file size exceeded" different from "image size too large"?
- No. Both mean the file in bytes is over the cap, and both are fixed by compressing. The wording that does mean something different is anything mentioning pixels, width or height — that is a dimensions problem, and the pixel-limit page handles it.
- The upload still fails after I compressed it
- Check three things. That the number you entered is the form’s real limit rather than a guess. That you uploaded the downloaded file and not the original still sitting in your folder. And that the form is not rejecting for a second reason at the same time — many portals check size and dimensions together but only report the first failure.
Still rejected? Troubleshooting
- The limit is in MB
- Portals disagree on what “1 MB” means — some use 1,000 KB (decimal) and others about 1,024 KB (binary). Enter the limit as stated on your form, then target comfortably below it rather than sitting on the boundary.
- Still too large after compressing
- Set a KB value about 10% below the stated limit to leave a safety margin — for a “1 MB” cap, target roughly 950–990 KB.
- The error says input image exceeds pixel limit
- That is a dimensions problem, not a KB problem. Open the fix input image exceeds pixel limit task (/tasks/fix-image-dimensions-invalid) to resize to the required width and height.
- The form also rejects my aspect ratio
- Many portals require a specific width:height ratio (e.g. passport head-and-shoulders). Enter the required pixel dimensions in the checker so resize and compress happen together.
- The photo looks too soft at the limit
- Crop tighter on the face so fewer pixels compete for the KB budget, or check whether the portal allows PNG instead of JPG.
Private by design. Your file is read and fixed entirely in your browser — it is never uploaded. You can verify this yourself.
