Why Your Collage Looks Blurry After Export, and How to Fix It

The most common cause of blur is exporting at a smaller size than the final display. If a collage will be viewed at 1080 pixels wide, the export should be at least that wide; enlarging a small export later only multiplies the softness.

Work backwards from the destination: social feeds usually want 1080 to 1440 pixels on the short edge, while print needs far more. Set the canvas size before fine-tuning the layout so cropping decisions are made at real resolution.

A grid is only as sharp as its most stretched cell. A 600-pixel photo stretched into a 1000-pixel cell will look soft even if every other image is crisp. Zoom into each cell at 100% before export and replace or shrink the weak ones.

Screenshots deserve special attention: they contain hard edges and text that reveal scaling immediately. Keep screenshots at or below their original pixel size whenever possible.

JPG compression softens fine detail and adds artifacts around text and edges; PNG keeps edges exact at the cost of file size; WEBP sits between them. If text or UI elements look fuzzy, the fix is usually switching from JPG to PNG, not increasing resolution.

Remember that platforms re-compress on upload. Exporting at slightly higher resolution than required gives the platform's compressor more to work with and usually survives the second compression better.

First, open the exported file at 100% zoom, not the editor canvas. If the export looks fine at 100% but soft on the platform, the platform's compression or display scaling is the cause, and the fix is exporting larger or in a different format.

If the whole image is soft at 100%, the canvas was exported below its display size. If only some cells are soft, those source photos are too small for their cells; the rest of the pipeline is fine.

If text and hard edges show ghosting or ringing artifacts, the format is the problem. Re-export the same canvas as PNG and compare; when the PNG is clean, the JPG quality setting was the culprit.

Start collages from original photos, not images forwarded through chat apps. Messaging platforms silently re-compress and downscale, and a collage built from forwarded images inherits all of that damage.

Avoid stretching any image beyond roughly its original pixel size. When a photo is too small for the cell you want, give it a smaller cell or let background color absorb the difference instead of scaling up.

Keep one master export at full resolution. When a platform needs a smaller or different version, derive it from the master rather than re-exporting from an already-compressed file.

Take one sharp photo and build a two-cell collage: place the original in one cell and a deliberately small copy stretched to fill the other. Export and view at 100% to learn exactly what scaling blur looks like.

Export the same collage three times: PNG, high-quality JPG, and low-quality JPG. Zoom into any text or hard edge in all three files. After this comparison you will recognize compression artifacts on sight.

Send one export to yourself through a chat app, then compare the received file with the original. Seeing the platform's silent re-compression once explains why master files should always be kept.

Export is not the last technical step; it is part of the design. The wrong format can soften text, remove transparency, inflate file size, or make sharing harder.

Keep a small export matrix for your own work: format, quality setting, target platform, and final file size. After a few projects, you will know which settings work instead of guessing each time.
