See for yourself by reading reviews on the most popular resources:
The ease and operation was fantastic. I get confused very easily with all the new technology. With PDFFILLER I was able start at file I found in the browser and fax it, import a file and email it without any trouble. I will be using this a lot.

Didn't expect a trial... kind of took me by surprise after I used it to file a larger pdf. I like the software but the tactic is a little... predatory?

So far
So far, so excellent. User experience takes a little getting used to, but a quick google shows you how to do it. And I haven't found anything yet that it wont do. Great tool. Used it for about 40 documents so far. Splicing things together, re-wording and cutting and changing dates. Basically editing everything imaginable in pdf.
2022-05-07

What is the fastest way to seal an envelope?
Warm water works better than cold water. If you have many envelopes to seal, keep a sponge or similar material handy. An alternative to the wet sponge is your finger. Just dip it into a gas of water.

How do you seal an envelope?
Swipe your tongue carefully across the seal of the envelope. Seal the envelope. Fold the flap down, and then run your fingers over the top to set it in place. The wetness from your tongue will moisten the glue on the seal, allowing it to bond with the paper of the envelope when sealed.
Do you have to seal envelopes?
Sealing the envelope is just as important as using the correct address with the proper Zip Code and affixing the correct postage, Camp says. It may seem like a simple oversight, but one unsealed envelope potentially can cause us a lot of maintenance issues and delay the delivery of our customers' mail.
Can you use a glue stick to seal envelopes?
For a simple method that probably doesn't require a trip to the store, you can seal your envelopes with a glue stick. Simply run the glue stick along the sealing portion of the envelope, then press firmly to seal. It doesn't get much easier than that.

What can I use to seal envelopes?
Use a cotton swab or Q-tip. Dip the end of the swab in a small bit of water in a cup. Envelope Moisteners work brilliantly. These hand-held beauties have liquid glue inside, or allow you to simply put water in them. Glue Sticks good ole envelop glue will do the trick.
Is it safe to lick envelope glue?
Detain adhesives are made from potato or corn starches, which makes the glue safe to lick. There are even people who refuse to lick envelopes out of fear of a tongue paper cut (or in some cases a rather tenacious urban legend about cockroach eggs). But tongue or sponge, the effort required is about the same.
