Upscale a JPG without magnifying the compression
Every JPEG carries the damage of its own compression — blocking in flat areas, ringing around edges. Enlarge one straight and you get four times as much of it. Clean first, then enlarge.

What compression actually leaves behind
JPEG throws away detail in 8×8 pixel blocks, and it throws away more in the areas your eye attends to least. That is a good trade at full size and a bad one the moment you enlarge, because the enlargement has no idea which structure came from the camera and which came from the encoder.
Two artefacts matter:
- Blocking. Flat regions — sky, a studio backdrop, a wall — break into faintly visible squares. Enlarged 4×, those squares become 32-pixel tiles.
- Ringing. High-contrast edges get a faint echo on either side. Enlarged, the echo becomes a visible halo, and it survives sharpening because the sharpener reads it as real edge structure.
Both are worst in JPEGs that have been re-saved repeatedly — anything that has been through a chat app, a marketplace resize, or an email round trip.
Judge the source before you pick a mode
Open the file at 100% and look at a flat area and a hard edge.
- Blocking or halos visible → the file is damaged. Run Unblur & Restore first. Its restoration pass is built for this, and it will enlarge 2× in the same run.
- Clean but soft → no damage to repair, just a lens or a small original. Go straight to Ultra Upscale 8X at 4× or 8×.
- Clean and sharp, just small → Ultra Upscale 8X at 8×. Nothing to clean.
Getting this order right is most of the outcome. Enlarging a damaged JPEG makes the damage structural; cleaning after enlargement means the cleaner is working on artefacts four times bigger than the ones it was tuned for.
Pro tips
- Find the original. A 2 MB JPEG straight from the camera beats a 200 KB copy of the same shot, however good the upscaler. The reconstruction can only work from what survived.
- Never round-trip. Do not export the result back to JPEG at 80% quality and call it done — that adds a fresh generation of the damage you just paid to remove.
- Screenshots of JPEGs are the worst case. Recompressing a compressed image on a scaled display gives the model two incompatible sets of artefacts to reason about.
- Cost: Unblur & Restore is 1 credit at 1×, 3 at 2×. Ultra Upscale 8X is 3 at any scale.
FAQ
Questions, answered.
Why does my JPEG look worse after enlarging elsewhere?
Because the artefacts were enlarged too. A generic upscaler cannot tell an 8x8 compression block from real image structure, so it reconstructs both faithfully.
Do I get a JPEG back?
No — output is PNG. Re-encoding a freshly reconstructed image as JPEG would add a second generation of exactly the damage you came here to remove. Convert afterwards if you need to.
How big a JPEG can I upload?
50 MB for Creative Upscale, 20 MB for Ultra Upscale 8X and Unblur & Restore.
Can I do both passes?
Yes. Restore first at 1x, download, then run Ultra Upscale 8X on the cleaned file. That is two runs and two charges, but it beats enlarging the damage.
