2, use high-quality image editing software: such as Photoshop or GIMP, they have a variety of tools that can help you optimize and improve the quality of the image.
3, use the appropriate scale ratio: do not magnify the image to more than twice its original size, otherwise it may cause the image to become blurred.
4, convert the image to the gray mode: this can reduce the color information in the image, so as to avoid magnification
After blurred.
5. The noise of the image down: The use of the noise reduction tool can reduce the noise in the image, thus making the image clearer after magnification.
hope these methods can help you magnify the image without making it blurred.
How to make the photo magnify but not blurred?
uses image processing software that supports "Keep Details 2.0" function, such as Photoshop, to enable detail preservation algorithms, adjust image size parameters and control blurred, to image preservation after magnificationThe specific operation is as follows:
Activate the detail retention function Open the image processing software (like Photoshop for example) and select the photo you want to enlarge. Press Ctrl+K To enter the preference settings, select "Enlarge reserve details 2.0" in the "Technical preview" option. The function analyzes the edges and textures of the image through intelligent algorithms to keep the original details as much as possible when enlarged, reducing the ambiguity.
adjust the image size parameter execute the "image size" command in the "image" menu, change the unit to percentage. In the width and height input box, you can set the magnification multiplier (theoretically supported up to 200 times, but actually recommended rational selection according to photo resolution, such as 150% or 200%) at this time the software will re-calculate the pixel distribution based on the "reserve details 2.0" algorithm, avoiding the edge blurred caused by traditional plug-in methods.
optimized blur controlIn the image size adjustment interface, find the "reducing the blur" option, adjust its value to 15 or around. The parameter balances detail retention and noise suppression: too low values can cause the image to feel particulate after magnification, too high values will be too smooth details. After clicking on "Determinate", the software will complete the final rendering.
note that the higher the original photo resolution, the better the effect after magnification (such as 300dpi or more)
If the software does not have the “Restore Details 2.0” function, you can try other professional tools (such as Topaz Gigapixel AI), its deep learning-based amplification technology can also effectively reduce the blur. After amplification, it is recommended to fine-tune the edge with the “Augmentation” tool (such as Photoshop’s “Intelligent Augmentation”) to further enhance the clarity, but avoid over-Augmentation that causes the image to become hard.
The solution for image enlargement is to use image non-loss enlargement technology to image size enlargement and clarity through professional software tools. Here are the specific operating steps and instructions:
No Loss Amplifier” software.
2 operating steps add image file
install and open the software, click the Add file button, select the image you want to enlarge; or directly drag the image into the software interface with the mouse.
note: adding too many images at a time will extend the processing time, it is recommended to batch processing.

No-loss magnification algorithm (effect is close, select one).
noise reduction : adjusted according to the image noise situation (if the original picture is clean can be set to low, noise is set to high).
magnification multiplier : selected according to the requirements (such as 2 times, 4 times, the higher the algorithm requires multiplier).

The software starts processing the image with the red button in the upper right corner, the software starts processing the image with the red button. After the processing is completed, the tip box pops up and the blue button is clicked to view the image after the magnification. The
effect by comparing the original image with the image after the magnification, visually seeing the clarity of almost no difference, avoiding traditional magnification ambiguity.
Intelligent supplementation lacks detail, rather than simple stretching pixels. Applicable scenes :
need to magnify low-resolution images (such as old photos, web materials) to maintain clarity.
printing, design, etc. Scenes that are highly demanding for image quality.
with traditional magnification differences :traditional methods (such as Photoshop direct stretching) will be blurred due to pixel plug-ins.
0 no-loss magnification is optimized by algorithms, retaining detail while magnifying, and image quality is virtually free of damage.p>4, note image base quality: if the original picture itself is blurred or too noisy, the effect of non-loss amplification will be limited (the algorithm can not generate details by emptiness). amplification multiplier limit: it is recommended to choose reasonable multipliers according to the original resolution of the image (such as the original image 1000x1000 pixels, magnification to 4000x4000 pixels as a reasonable range). software choice: in addition to the "high-speed image non-loss amplifier", you can also try other professional tools (such as Topaz Gigapixel AI, Bigjpg, etc.), operating logic similar.
through the above method, can effectively solve the blurry problems after the image enlarged, meet the scenario requirements for the high quality of the picture.
the quality of the photo is selected for the highest pixel and then uploaded to the computer.
the low-phase photo, in a certain size range, is felt very clear. the enlarged is no longer clear, to the computer, there is also a certain relationship with the resolution of the computer graphics, the photo itself is not high-phase, to the monitor, and the viewers view the picture is even bigger than the phone, the high-phase and low-phase image.
The higher the phosphorus, the less the clarity, the higher the distortion after the magnification.
is very vague reason is:
1, the cell phone screen is much smaller than the computer screen.
2, the resolution of the cell phone screen is smaller than the resolution of the computer screen.
3, the pixel setting is lower when shooting, on the computer is shown, equivalent to being magnified, there will be a mosaic, looks more vague.

The display device can effectively distinguish the smallest indication difference. The resolution of the monitor is 80DPI refers to the effective display range of the monitor, the display imaging device can generate 80 light points per inch on the fluorescent screen.
0 For example, a 14-inch monitor (the fluorescent screen angle length is 14 inches), the point range is 0.28mm, then the resolution of the monitor is = 25.4mm/inch÷0.28mm/Dot≈91DPI (1inch=2.54cm).
displays generally do not indicate the DPI value that characterizes the resolution of the display, but only give the point gap. We can calculate the resolution of the display according to the above formula. Based on the DPI value we calculate, we can calculate the highest display mode that the display can support
. Assume that the 14 inch monitor fluorescent screen effectively displays the length of the angle of the screen is 11.5 inches, because the proportion of the horizontal direction and vertical direction of the display is 4:3, so an effective display range level can be set.
The width is 4 x inches, the vertical height is 3 x inches.
According to the mathematical equation theorem, x=11.5÷5=2.3 inches. So the effective display range is 2.3×4=9.2 inches, and the vertical height is 2.3×3=6.9 inches. The maximum display mode is about: 800 (9.2×90)×600 (6.8×90), this is the point (Dot) representing a pixel.
