How do I upscale an image online?+
Upload a JPG, PNG or WebP file on this page, choose 2×, 4× or an available resolution and review the displayed pixel dimensions and credit cost. Start processing, tap the zoom comparison to inspect the original and enlarged result, then download the format you need. You can choose another photo from the result panel without leaving the tool.
Is this image upscaler free without signup?+
Eligible guests can use their available shared daily credits without an account, with 2× and up to 2K output. This is the same guest allowance used by other eligible tools, not a separate grant for this page. Daily credits reset at midnight UTC without rollover; lifetime and daily IP limits also apply. The workspace shows the remaining balance and exact task cost. Signed-in users spend account credits; 4× requires an account and larger resolution targets require a qualifying subscription.
What is the difference between 2×, 4× and 4K?+
2× doubles both pixel dimensions; 4× quadruples them. A 960 × 540 image becomes 1920 × 1080 at 2× or 3840 × 2160 at 4×. 4K describes a resolution, not a multiplication factor. The tool preserves your aspect ratio, so a square image does not become a widescreen wallpaper.
Can I enlarge a photo without losing quality?+
AI estimates edges and textures as it adds pixels, but it cannot guarantee recovery of missing information. Compression blocks, severe motion blur and tiny faces can remain imperfect. Keep the original and compare meaningful details, including eyes, logos and lettering. A larger file alone is not evidence of a better image.
Why is my requested output too large?+
A guest can select 2× and up to 2K. 4× needs a free account, and resolution targets above 2K need an active subscription: Starter reaches 4K, Pro 8K and Ultra 16K when the original has enough detail and the model can reach the target in at most three passes. Factor mode has its own output ceiling. The tool shows the expected dimensions and the server checks both your plan and the file before charging.
Will it make a print-ready 300 DPI image?+
Print size depends on pixel dimensions divided by PPI. A 2400 × 3000 image covers 8 × 10 inches at 300 PPI. This tool shows an estimated size but does not set printer profiles, paper settings or DPI metadata. Confirm requirements with the print shop and review a proof before ordering a large print.
Do I pay again to download another format?+
No. The credit charge covers the processing task. At moderate sizes you can export PNG, JPG or WebP from the same completed result without another AI request. Large 8K and 16K outputs download as original-size JPG files so the browser does not have to re-encode hundreds of millions of pixels. Keep a local copy before your result expires.
Are my photos private, and what happens if processing fails?+
Files are stored privately and result access is checked against the owning account or guest session. Processing sends the image to our AI provider. Guest results are normally retained for one day and account results for seven days. Failed tasks return their reserved credits or free allowance; a network interruption may need time for the task status to settle.
How much can you upscale before quality degrades?+
There is no universally safe multiplier. Start with the smallest output that meets your placement or print requirement, then inspect meaningful detail at 100% zoom. A clean source may give a useful 4× result, while a compressed thumbnail can remain imperfect even at 2×. Compare texture, lettering and faces with the original; more output pixels do not prove that missing detail was recovered.
Why do AI upscales sometimes look plasticky?+
AI can replace ambiguous texture with plausible-looking detail, which may make skin, fabric or foliage look too smooth. The effect depends on the input and processing settings. Compare the same areas at a useful display size, try a smaller enlargement when it meets your goal, and keep the original if the result loses meaningful texture. Sharper-looking or larger output is not automatically more accurate.
