If your recipient plans to view your photos on-screen and/or does not have the need for professional print quality, you can and perhaps should take advantage of WinZip's resize feature with Zip and E-mail. This will allow you to send multiple photos in one Zip file and it will neither take forever for your recipient to download it nor will it clog their inbox. It will also be much more convenient for your recipient to download one Zip file rather than several separate attachments.
In the WinZip Express dialog, you can type the name you want, click the Reduce photos box, choose at least one thing under Share/Save Options, and then click Create New Zip File to send and/or save your resized images in a Zip file. With WinZip Express, you have many other options available as well, including applying a watermark to your photos. Starting with WinZip 22.5, you can save your WinZip Express options, chose to both save and schedule this action, and reuse options you saved at an earlier time. Scheduling files for deletion is another new option, but is not available here, as the Zip file is being emailed and is not being saved.

"Zipped" or "Compressed" files are often sent as email attachments. The compression process helps to reduce file size. View the help page on how to Zip (Compress) Multiple Files if you would like instructions on creating a zipped file.
Image compression may be lossy or lossless. Lossy methods are especially suitable for natural images such as photographs (e.g JPEG files) in applications where minor (sometimes imperceptible) loss of fidelity is acceptable to achieve a substantial reduction in bit rate.
JPEG optimizing is considered to be a very efficient method to reduce JPEG file size while preserving the image quality. The goal is to reduce the size of photos without affecting their perceptual (noticeable) quality. The optimized image should look identical to the original image to humans, even if it was reduced to 30% of its original size or even less.
ZIP uses many compression algorithms including the popular DEFLATE compression and is used to reduce the total size when sending files over the internet. You can also zip files to save more disk space, which is ideal for portable device users. ZIP files also support encryption and split archives, offering a perfect way to organize and store your files.
Most people compress files into a zipped folder to save space without losing data. For instance, if you want to send many audio, video or image files over the internet, you can compress them into a ZIP folder to reduce the total size and bandwidth required. However, zipped folders have many other benefits including better encryptions and archiving.
Acrobat reduces the size of a PDF file without compromising quality. The Acrobat PDF compression tool balances an optimized file size against the expected quality of images, fonts, and other file content.
PDF Optimizer provides many settings for reducing the size of PDF files. Some of the PDF Optimizer settings are comparable to the settings that are available when you create a PDF file using Distiller. Whether you use all of these settings or only a few depends on how you intend to use the files and on the essential properties a file must have.
Auditing the space usage gives you a reportof the total number of bytes used for specific document elements,including fonts, images, bookmarks, forms, named destinations, andcomments, as well as the total file size. The results are reported bothin bytes and as a percentage of the total file size.
Adobe is testing the reduce file size experience in the Optimize PDF toolbar under two different names - Reduce File Size or Compress PDF. Therefore, after updating to the latest release, you see either the Compress PDF option or the Reduce File Size option. From the functionality perspective, both the options are the same.
Reduces file size by eliminating unnecessary pixel data. In general, JPEG and JPEG 2000 compressions give better results on images like photographs with gradual transitions from color to color. ZIP is the better choice for illustrations with large areas of solid, flat color, or patterns made up of flat colors. For monochrome images, JBIG2 compression, which is available in PDF Optimizer but not in Distiller, and it is superior to CCITT.
Available only for JPEG and JPEG 2000 formats. JPEG and JPEG 2000 compression methods are typically lossy, a process that permanently removes some pixel data. You can apply lossy JPEG or JPEG 2000 compression to color images at various levels (Minimum, Low, Medium, High, Maximum). For JPEG 2000 compression, you can also specify lossless so that no pixel data is removed. Compression for monochrome images is lossless, except for JBIG2 compression, which provides both Lossy and Lossless modes of compression.
Available only for JPEG 2000 format. Divides the image being compressedinto tiles of the given size. (If the image height or width is notan even multiple of the tile size, partial tiles are used on theedges.) Image data for each tile is individually compressed andcan be individually decompressed. The default value of 256 is recommended.
If your PDF includes artwork that contains transparency, you can use presets in the Transparency panel of PDF Optimizer to flatten transparency and reduce file size. (Flattening incorporates transparency into corresponding artwork by sectioning it into vector-based areas and rasterized areas.) PDF Optimizer applies transparency options to all pages in the document before applying other optimization options.
Removes named destinations that are not being referencedinternally from within the PDF document. Because this option doesnot check for links from other PDF files or websites, it does not fitin some workflows.
Sometimes, the file size of your PowerPoint presentation can get very big. In some cases, that can be annoying, e.g. when trying to send the slides via email, but not being able to do so because the file is too large. Usually, pictures and videos are the reason why presentations become too big. The good news are that you can easily compress pictures and embedded media files by following the steps listed below.
PowerPoint offers the option to compress all images at once or choose single pictures to reduce their file size. Keep in mind, that compressing an image will automatically reduce its quality as well. If you don't need to reduce the file size, better use the highest quality resolution as possible.
Video and audio files can increase your PPT size a lot. It's a good idea to compress those if you want to make some space. Some PowerPoint versions make it possible to decrease the media size in PPT but if this option is missing in your program, online video compressors are the solution.
There are plenty of online video compressors which you can use to reduce the video size in advance. For example, the website FreeConvert makes it easy to decrease the file size without having to download anything. This way you can integrate a smaller media file into PPT.
By converting a PowerPoint file into a PDF, the size will reduce automatically. During the process, images get compressed and some media (audio, videos, 3D models..) get removed. If you want to change the PowerPoint slides at all time, this method might not be the right one for you, as PDF files can't get edited the way a PowerPoint can. Hence, converting PPT into PDF only makes sense if your presentation will work as a handout and if the PDF files options are enough for you.
The Office 365 subscription makes it possible to add 3D models to your PowerPoint slides. Nevertheless, those media require much space since they transport a lot of information. In order to minimize the PPT file, exchanging the 3D model with a normal image will easily reduce the size of your PowerPoint file.
If you need to share your PPT with someone, a ZIP- file format might help you to reduce the size of the PowerPoint. Even though, this method can save some place temporally, it might not be enough to send it via email. Uploading it to file-sharing platforms, such as GoogleDrive, DropBox, OneDrive or other websites and sharing its link to download the PPT, can be the better option. (Using an USB for sharing the presentation without the need to decompress anything would be the best solution)
There are several ways to reduce the file size of a PowerPoint. You can compress images, videos and audios, convert your presentation into a PDF file, get rid of 3D models or compress the PowerPoint as a ZIP-file. We explained for you how all of this works in our blog.
To compress videos in PowerPoint, go to "File" in the PowerPoint menu and then click on "Info". Then open the drop-down menu "Compress media" and select the size of the compression file. Be careful not to reduce the quality too much and check that the quality of your video on the projector you will be presenting on is not too bad.
Hi, I saw in a tutorial in youtube how to compress file using 7zip. One example shown was a 4gb file compressed to 800 mb . I tried it on my end to compress a 1.37 gb file and I was expecting it to be smaller in size but I got the same file size as the original. Why is it like that?
This article does not cover splitting up large files. We do not yet have a guide for that, but I did find a tutorial for you that goes over how to do this. Check out How to split large files with 7zip and see if that helps you. We have not tested the guide, nor do we endorse the site, it was just something I found when searching the web.
The amount of compression will vary depending on the file and its type. For example, text files (htmp. php,etc) can usually compress somewhat. Some files such as image and pdf files do not compress much at all. As for the types of compression available in 7-zip, I tested a txt file with each type. The top 4 compression formats, starting from the smallest, are .xz, .7z, .gz, and .zip. The difference between each was very small, so all formats will be fine. 2b1af7f3a8
