What Our Image Quality Enhancer Can Do
01
Sharpen Blurry Photos
Camera shake, out-of-focus shots and compressed images all lose edge detail. Our AI image enhancer rebuilds those edges instead of just increasing contrast, so hair, fabric and text come back crisp — not crunchy.
02
Upscale Images to HD and 4K
Increase image resolution up to 4K on the free plan, or 8K on paid plans, with a maximum output of 16K, without the pixelation you get from traditional resizing. The model predicts the missing pixels rather than interpolating them, which is why photos stay natural at 4x.
03
Fix Low-Quality Photos Online
Old scans, screenshots and downloaded images often carry heavy JPEG artifacts. Upload them here to clean up noise and banding, then download a high resolution image — this is the image quality enhancer step that removes artifacts before resizing — ready for a website, a listing or a print job.
04
Make Photos Print-Ready
Prepare images with enough pixel dimensions for posters, business cards and large-format output. Enhance your source before sending it to a printer instead of relying on basic interpolation.
05
Batch Enhance Multiple Images
Processing a whole folder? Upload several images at once and apply the same enhancement settings to keep the look consistent across your catalogue.
06
Works with JPG, PNG, WEBP and HEIC
No conversion dance. Drop in photos straight from your phone or camera — HEIC included — and download in whichever format you need.

Frequently Asked Questions
Is HD Image Enhancer really free?
Yes — you get 30 free credits every day without creating an account. Each image costs 4 credits, so that's 7 free images a day, and credits reset at 00:00 UTC.
What is an image quality enhancer?
An image quality enhancer is a tool that rebuilds lost detail in a photo — sharpening edges, removing compression artifacts and raising resolution — rather than simply enlarging the pixels.
Do I need to sign up?
No. Anonymous uploads are supported at limited resolution. Signing in raises the limit and lets you keep a history.
What is the maximum resolution I can get?
Free plans can output up to 4K. Paid plans output 8K, with a maximum output of 16K.
Will enhancing reduce my image quality?
No. Enhancement reconstructs detail rather than stretching pixels, so edges stay sharp and textures stay natural instead of turning into blocks.
Can I upscale an image to 4K?
Yes. Free plans can output 4K. Paid plans output 8K, up to a maximum of 16K. Note that true 4K detail depends on the source — a 200 px thumbnail cannot become a sharp 4K photo.
What's the difference between an image quality enhancer and an upscaler?
An upscaler only enlarges an image, so a low-resolution file becomes bigger but just as soft. An image quality enhancer also rebuilds the detail — sharpening edges and removing compression artifacts — before it raises the resolution, which is why the result stays clean at 4K.
Which file formats are supported?
JPG, JPEG, PNG, WEBP and HEIC for uploads; PNG, JPG and WEBP for download. HEIC photos from iPhone can be uploaded directly.
Can I enhance more than one image at a time?
Yes. Batch upload is available on paid plans only.
Is my photo safe?
Files are encrypted in transit and deleted automatically after processing. We never use customer images to train our models.
Does it work on mobile?
Yes. The tool runs in any modern browser — iOS Safari and Android Chrome included — with no app install.
What's the difference between the free plan and paid plans?
Free covers 30 credits a day (4 credits per image, 7 images) at up to 4K. Paid plans unlock 8K output, up to a maximum of 16K, plus batch processing and priority speed.
