Security is paramount to Adobe. If you don't sign in or save your file, it will be deleted from our servers to respect your privacy. Security measures are also built into every PDF created with Acrobat.
The Acrobat online PDF compressor balances an optimized file size against the expected quality of images, fonts, and other file content. Just drag and drop a PDF into the PDF compression tool above and let Acrobat reduce the size of your PDF files without compromising quality.
For more refined control of optimization settings, you can try Adobe Acrobat Pro for free for seven days. Acrobat Pro lets you customize PPI settings for color, grayscale, and monochrome image quality. You can also use PDF editor tools, edit scans with OCR functionality, convert PDFs to Microsoft PowerPoint and other file formats, convert PNGs and other image file formats, organize and rotate PDF pages, split PDFs, optimize PDFs, and more. You can use Acrobat on any device, including iPhones, and on any operating system, including Mac, Windows, Linux, iOS, or Android.
I'm using Final Cut Pro X. I have a number of 20 minute videos and am trying to reduce the file size after exporting. Each 20 minute video is exporting to about 2 gigs. Is there a way to compress/ reduce the file size without losing much quality? I do have compressor as well, but haven't found a great solution yet. Any help is much appreciated. Thanks in advance!
As far as resolution and frame rate, I am not sure. I am streaming the videos from vimeo (using the PRO account). The videos are then accessed from my website, which is a membership website. I am trying to find the balance between keeping the video quality high, but with a small-ish file size for the 20 minute videos. The videos will be streamed on all devices including desktops and phones. I am shooting in 1920 x 1080 HD on a canon 80D.
Right now to export, I am using the share button>master file> H.264. This has yielded the smallest file size while retaining quality, but would like to see if there is another way to get the file even smaller, while retaining quality.
Is there a specific reason you need the smaller file size? When you upload a video to Vimeo, it creates multiple versions in different formats and streams the appropriate version to the device viewing it automatically:
Thanks AI I am going to look into this. Right now I am using the share button>master file> H.264. This has yielded the smallest file size while retaining quality, but would like to see if there is another way to get the file even smaller, while retaining quality.
That is very helpful! I didn't realize that vimeo factored all of this in when choosing what video file to deliver to the user via the stream. It sounds like I should keep uploading the 2 gig videos and let Vimeo handle the rest. Thanks Meg!
Hi there:
I have a question about the file size for something that is going to be printed on merchandise that I am selling via print on demand. I am using Affinity Designer v2 on desktop, and I also have Affinity Photo.
I am creating car seat covers with the following dimensions and specifications: 2993 x 7703 pixels, CMYK and 150 dpi. The maximum size of the image file to be used by my supplier for printing is to be no more than 20 M (either in a JPG or PNG format with the sRGB color profile).
I noticed that when I use a background that has a texture to it or that is more complicated, the file size for the image (JPG) gets larger than the 20 M that is allowable. Usually I fall into the allowable size with my designs, but now I have a car seat cover that I am working on that is exceeding 50 M.
My question is: how do I reduce the file size of my image file without losing the printed quality of the design?
Looking forward to your response.
Thanks so much.

Upsate: I had to go down to 80 percent to get the files size to be uploadable. My print partner said that the result was blurry in some parts. I guess the background is too busy, being a bit large and all. That said, I think I will have to make a new one that is less complex.
Thanks anyway. Trial and error I guess
@nickbatz Thanks ... they are not vinyl, they are a polyester blend, printed via sublimation. I think they want 150 dpi. Perhaps 75 would be too low.
I think my best route is to redo the background to get a more simpler effect.
@Pšenda Good to know. However, the file size increased with the multiple elements in the design. Usually when my background is complex, I get a larger file size when exporting to jpg or png, which means that I am unable to upload the design to my print on demand dashboard. As I lowered the quality in the settings during export, it seemed to have created blurriness in my overall design, according to my print partner. I guess that was my issue.. Most of my elements were vector. So I think that there was further pixelation that incurred blurriness.
@nickbatz Not sure why you are referring to this ... you must be posting on the wrong thread. I never uploaded those and they are not mine. Please reread the main post.
Oh sorry, you tagged another person in this to demonstrate something.
Please indicate their resolution (ie how many pixels they have), the DPI size is not important. As OP write, the target resolution of his image is 2993 x 7703 pixels, and they will remain whatever the DPI is. For a JPEG file, the DPI value is just an entry in the metadata.
Yes, but that's not the OP's case - please read his first post, where it says that the resolution of the image is given and fixed (2993 x 7703 pixels), so there's no point in discussing the obvious fact that if I increase the resolution, I will of course increase the file size.
never the less, 20 Mbyte is quite generous for the given pixel count. I create a test file where I added noise, with 100% quality it was 25MB, with 95% it was 15MB. The visual quality difference will be detectable when comparing 100% zoomed, but normally irrelevant when printed out.
So it's pretty much a matter of semantics. Regardless of what's actually happening, you can lower the DPI and file size at a cost to the resolution that may or may not matter (probably not) if you're printing a car seat cover.
It all worked great and the file size is now down to 4Mb, only problem is that the text is starting to blur. Since it appears that text makes up for only about 3% of the total file size (it's the images that are bloating up the Mb count), I was wondering if it's possible to reduce the image quality without "touching" the text layers.
In powerpoint you can have a bad quality background image and write perfectly sharp text on in. Even at 640x480 text looks good in powerpoint. On the contrary, if I lower the res in photoshop, the text turns crappy.
UPDATE: after a long afternoon of work, and thanks to John's help, my presentation is now perfect, so I thought I'd give back to the community an share a couple more things I've learned working on this project.
As you can see, like John said, if you have faux styles applied, the text is automatically rasterized and this creates a lot of artifacts during the conversion. On the contrary, if there are no faux styles, the text stays in its vector form and, even when you reduce the image quality a lot (see the picture on the right side of the image), the characters remain tack sharp.
So I went ahead and re-formatted all the text boxes in my presentation. Again something went wrong see here. As you can see, sometimes the PDF version screws up your text. As silly as this may sound, I found that this only happens when you write too much text in a single box. All text longer than 6 or 7 lines got screwed up. Splitting it into two different text boxes with 3 lines each fixed this. The same problem happened on multiple slides, and the same solution worked to correct the problem on all of them.
Last but not least, I managed to decrease the total file size some more by going to file->Automate->PDF presentation (not sure about the exact translation cause my photoshop is in italian) instead of the usual file->Save As->Photoshop PDF. Try for yourself, with the same compression values the first option yields smaller files (some 30-50% smaller!!). So I guess there's some hidden parameter that the "Automate" command sets somewhere that the "Save As" does not.
The reason your text is not being exported as vector is because you've got some of Photoshop's "Faux Styles" applied to your text. Any time you have one of these (Faux Bold, Faux Italic, Small Caps), the text will get rasterized in the PDF.
I have a few high res TIFF files I'd like to reduce in size as they are currently around 20 MB, but need to get them down to no more than 10 MB so I can upload them to a website. Is there a way I can do this without converting them into JPEG files to avoid losing too much quality?
I would recommend you to use the bulk tiff image compression online tool developed by IMGCentury. I personally tested upto 500MB sized single tiff image which is compressed without any issue. But the compression took almost 2 minutes and ready to download. No images have been upload to the server for the compression. Find more information here: -compressor/compress-tiff/
