How to delete all small images inserted on each page?

If these are true images (with an xref etc.) you can delete them via page.delete_image(xref).
This actually is a replacement with a super-small transparent pixmap.

Otherwise you can use redactions, which now can also erase vector graphics (v1.24.0).

Can you share a full code to remove for example above file?

[JorjMcKie]

for page in doc:
    for i in page.get_images():
        page.delete_image(i[0])

[nissansz]

thank you, how to add a condition to exclude some images, like speicified width, height etc.

[JorjMcKie]

Look at the documentation of page.get_images() output, i[0] is just the xref of the whole item.

[nissansz]

images = page.get_images(full=True)

    for index, img in enumerate(images):

printed img info is like this: (30, 0, 396, 1034, 1, 'DeviceGray', '', 'Im2', 'JBIG2Decode', 0)
How to display this img?

[nissansz]

I can judge and delete now with below code.
'''

Import PyMuPDF

import fitz

File path you want to extract images from

file = "data.pdf"

Open the file

pdf_file = fitz.open(file)

Iterate over PDF pages

for page_index in range(len(pdf_file)):
# Get the page itself
page = pdf_file[page_index]

# Get the image list for the page
image_list = page.get_images(full=True)

# Printing the number of images found on this page
if image_list:
    print(f"[+] Found a total of {len(image_list)} images in page {page_index + 1}")
else:
    print("[!] No images found on page", page_index + 1)

# Extract images from the page
for image_index, img in enumerate(image_list, start=1):
    xref = img[0]
    base_image = pdf_file.extract_image(xref)
    image_bytes = base_image["image"]
    image_ext = base_image["ext"]

    # Save the image to a file
    image_filename = f"page_{page_index + 1}_image_{image_index}.{image_ext}"
    with open(image_filename, "wb") as img_file:
        img_file.write(image_bytes)

Close the PDF document

pdf_file.close()
