How to use
- Open bars-32x16.gif.
- Expect a 32 by 16 JPEG of the first frame.
- Expect white only if a pixel had been transparent.
Formula / how it works
The same bars GIF becomes a 32 by 16 JPEG. Only the first frame is kept. A transparent pixel would be painted white, because JPEG has no alpha. These bars are opaque, so the white-background sentence is a warning for the next file, not a change you can see in the red and blue halves.
Quality 80 and quality 60 are both offered. On this flat icon the file size barely moves. Read the size line on a real photograph. The pixel grid stays 32 by 16.
Use GIF to PNG when you need the frame without another lossy step. Use this page when the destination wants JPEG.
The first frame of bars-32x16.gif becomes a 32 by 16 JPEG. Quality 80 and quality 60 are separate runs. On this flat icon the size may barely move. A photograph is the file that will show the difference, and you should read the size line there. Transparent pixels would be painted white. These bars have none, so the warning is for the next GIF. Other frames are not included. GIF to PNG skips the extra lossy step if you need that.
White is the stand-in for a transparent GIF pixel, and these bars do not have one, so do not look for a new white bar in the sample. Look for 32 by 16 and a JPEG. Quality 80 and quality 60 are both valid runs. The size line tells you whether the second one was worth it. On a flat icon it may not be. On a photo it often is. Frames after the first are absent on purpose.
First frame only, 32 by 16, JPEG. Quality 80 and quality 60 are both on the form. The flat bars may not reward the lower setting. A photo often will. White replaces transparency, and these bars have no transparency, so do not hunt for a new white stripe. Other frames are omitted on purpose. GIF to PNG is the path that skips the JPEG generation when you can accept PNG.
Keep the GIF when the other frames matter or when a hole should stay a hole. The JPEG is one frame, 32 by 16, and a hole would be white. Quality 60 is worth trying on a photo and easy to ignore on these bars. The size line is the referee. The GIF file itself is not modified. The JPEG of these bars is 32 by 16. Quality 80 and quality 60 are both available. The flat colours may not reward 60. A photo might. Keep the GIF until you have read the size line on the file you care about. These bars are 32 by 16 either way, so they will not teach you the size lesson. Use a photograph when you want quality 60 to prove it is smaller.
Skip the extra loss with GIF to PNG.
Worked examples
GIF bars at JPEG quality 80
Inputs: g2j-f: bars-32x16.gif | g2j-q: 80
On this page, take bars-32x16.gif, then 80 and press Convert. A transparent GIF pixel would become white.
Result: GIF to JPEG: 32×16. Only the first frame of a GIF is kept. If a pixel was transparent, it is now…
GIF bars at JPEG quality 60
Inputs: g2j-f: bars-32x16.gif | g2j-q: 60
On this page, take bars-32x16.gif, then 60 and press Convert. A transparent GIF pixel would become white.
Result: GIF to JPEG: 32×16. Only the first frame of a GIF is kept. If a pixel was transparent, it is now…
Use cases
- Sending one GIF frame to a JPEG-only form.
- Keeping the 32 by 16 grid.
- Painting transparency white.
- Reading the size line on a flat icon before trusting a photo.
Tips & limitations
- Quality 80 and 60 may match on these bars.
- A photograph will differ.
- Only the first frame is kept.
- The bars are opaque, so the white warning is for the next file.
FAQ
What size is the JPEG?
32 by 16, from the first frame of bars-32x16.gif.
Where does transparency go?
Onto white. JPEG cannot store it. These bars had none.
Are the other frames included?
No. One frame, one JPEG.
Will quality 60 shrink a photo?
Often yes. These flat bars are a poor prediction. Read the size line.
Is a PNG available instead?
Yes, on GIF to PNG, without the extra JPEG step.
Is the GIF uploaded?
No.
The 32 by 16 JPEG is the first frame of bars-32x16.gif. An animation will not become a slideshow.
