Why is Add Text to Image not behaving as expected? Common causes
A short troubleshooting walk-through of the four most common ways Add Text to Image can frustrate you, and how to fix each one.
You've tried to compress / convert / process a image and the result is wrong — same size as before, broken, or just refuses to work. Frustrating, but the failure mode is almost always one of a small set of causes. Here's how to diagnose and fix each one.
Launch the tool: Add Text to Image — Everything happens locally in your browser — your file never leaves your device.
Cause 1: The image is already compressed
If a image has been compressed before — by a previous tool, by the source app, or by the platform that originally produced it — there's not much left to squeeze. Re-compressing a heavily-compressed JPG might save 2%, not 50%. Diagnosis: check the original file size against typical sizes for the content. Fix: accept the limit, or work backwards to find an earlier, less-compressed version of the source.
Cause 2: Embedded high-resolution content
A image that contains very large embedded images, fonts, or layers can stay huge no matter what you do — because the compression engine is working around those embedded blobs, not on them. Diagnosis: if a PDF / document is unexpectedly large, check whether it contains scanned page images at 600+ DPI. Fix: Add Text to Image has an option to downsample embedded images; turning it on usually solves this.
Cause 3: Wrong tool for the content
Some images need a specialised tool — a video needs a video compressor, not a general one; a vector graphic needs different handling than a raster. Diagnosis: check what's actually inside the file. Fix: Add Text to Image is built for images of this kind; if your file is a different format wearing the wrong extension, a converter step solves it.

Browser-only. Nothing is sent to a server.
Cause 4: Browser-specific issues
Very rarely, Add Text to Image fails because of a browser quirk — usually old browsers without WebAssembly support, or content blockers that interfere with the worker that runs the compression. Diagnosis: try in a different browser (Chrome / Firefox / Safari latest versions all work). Fix: if the issue persists, disable extensions in an incognito window and try again.
Cause 5: The image is corrupted
If the source image won't open in any program, no tool can compress it cleanly. Diagnosis: open the original in a stand-alone viewer or built-in OS preview. If it fails there, it's the file. Fix: find a clean copy or re-export from the original source.
Frequently asked questions
Why does my image stay the same size after compression?
Almost always because it was already aggressively compressed. The compression engine literally has no slack to remove.
My image works in other tools but not Add Text to Image. What's different?
Add Text to Image runs strict validation to avoid silently producing broken output. Other tools sometimes accept malformed input and silently corrupt it further.
Why won't Add Text to Image accept my file?
The extension might not match the actual content. Try renaming the extension to match what's actually inside, or run it through a converter first.
Add Text to Image crashed on my image. What now?
Try reducing the input — process fewer pages at a time, or split a giant image into smaller chunks. Mobile browsers especially have memory limits.
