Image enlargement guide
Choosing safe settings
Upscaling increases pixel dimensions but cannot recover every detail absent from the source. Clean originals generally produce better results than repeatedly saved images.
Choose a moderate scale first. Large enlargement increases processing time and may emphasize noise, halos or artificial texture. Compare at normal size and full zoom.
Quality checklist
Pay special attention to faces, text and straight edges. Use upscaling for presentation rather than as proof of new factual detail, and preserve the original.
Preview the export at its intended size. Keep the original until the new file has been checked. If an output looks blurred, return to a larger source instead of repeatedly editing a compressed copy.
Verify every result
Keep an original copy. Repeatedly opening and exporting a lossy file can introduce blur, ringing or block artifacts. Create new derivatives from the best available source instead of converting an already compressed copy again.
A practical selection checklist
Compression reduces storage and transfer time, but aggressive settings can soften text and fine edges. Preserve the aspect ratio unless a new shape is intentional. Crop first, resize second, then adjust quality.
A larger resolution label does not automatically mean a better-looking file. Learn what actually controls quality, size and compatibility before choosing an export.
Use descriptive names that identify purpose or revision. Avoid overwriting the source until the new file has been checked on the device or application where it will actually be used.
